SangSoo

SangSoo is the femslash ship between Han Sooyoung and Yoo Sangah from the Omniscient Reader's Viewpoint fandom.

Canon
Sooyoung and Sangah were initially enemies due to Sooyoung being part from the Apostles (the first one), allegedly the last person to stop reading Ways of Survival. Due to this info being leaked to KimCom by Kim Dokja himself, Sangah won an impression of the kind of person Han Sooyoung was; their enemy. This would change, though, when Sangah reappears after a time to Kim Dokja and Han Sooyoung. Not before gathering together to a safe place, Yoo Joonghyuk warns Kim Dokja by private chat of being careful with that woman (without specifying who), which makes Kim Dokja wonder who he was talking about as he looked at Sangah and Sooyoung running behind him.

While Sangah is unaware of Sooyoung, the latter asks about the constellation supporting the former, as it shouldn't be possible that she leveled up her [Agile Movement]'s skills so quickly even with a growth package. Sangah then asks about who she was, and Sooyoung introduces herself as the "First Disciple". This makes Sangah shock as she remembers the moments when the Disciples assaulted KimCom previously and killed the Chungmuro group, and is about to do the same with Sooyoung. However, she gets stopped by Kim Dokja claiming that she wasn't an enemy. They start discussing over and trying to find out the constellation supporting Sangah that made her strong quickly, since it was really suspicious even having a fabled constellation or a SSS-Grade growth skill. However, before even questioning her, they get interrupted with the begin of the next scenario, which was stopping the catastrophe. After this, Kim Dokja tells both girls that it wasn't time to fight, as they firstly had to clear the scenario.

Sangah and Sooyoung then team up together, and begin to fight the people that attempted on killing them and Kim Dokja. With Sangah's Ariadne's Web, she ruthlessly attacks the crowd chasing out for them, and Han Sooyoung notes this to Sangah when she's done. Sangah answers it being rich coming from her, and Kim Dokja monologues of how they made a good pair, with also noting that they talked like they hated each other. After the scenario is cleared, another disaster appears, a "returnee". When Sangah tries to restrain him with her stigma Ariadne's Web, the returnee escapes and Sangah is left fainted while still kneeling down. A scene later, Sooyoung is seen carrying an unconscious Sangah on her back with one of the clones while complaining to Kim Dokja why she had to carry whoever passed out, not getting an answer at all.

Sangah eventually regains consciousness and continues clearing out the scenarios along with the other party members. Sooyoung and Sangah still have a neutral bond while being part from the nebula as time progresses.

Their interactions are pretty minor after the Main Scenario 5, however they share significant contact in certain parts during the story, bit of discomfort between both but start to trust each other slowly.

When Kim Dokja and Yoo Joonghyuk were gone, it forced to leave Han Sooyoung in charge of Korean Peninsula inside the home of ‘Law of the Jungle’, an incarnation club of Gyeonggi Province. Leaving the room she was in, she sees Sangah waiting for her at the office doorway as this latter asks about her doing there. Han Sooyoung monologues how she had a "refreshing but very beautiful face", also adding that it was what the "media" had stated. Not before that she described in detail the outfit she was wearing, with the next quote: "As if conscious of the body that was revealed, she wore a wide coat on her shoulders". With a slight unfriendly look, Han Sooyoung wonders about she thinking that Sangah was busy with the TV these days, which wasn't the case at the moment. Sangah approaches to her, moving away from the wall she was leaning on while looking down at Sooyoung, being there a slight difference in their heights.

Sangah asks Sooyoung how long would her going to act like that, the latter asks what she's talking about, and Sangah details that she couldn't kill all of the people from Law of the Jungle just because the law and order is gone. Sooyoung waves her hands as she was lazy to explain, noting also that Sangah didn't know the type of people belonged to Law of the Jungle. In addition, she wouldn't know what would they do. Sooyoung tells her that they were ones that could do something wrong in the future, and Sangah pushes back that she didn't even give them a chance, and while passing by, Sooyoung replies that she didn't know anything, as everything was already determined. Before even leaving, Sangah mentions the book Sooyoung had created; Three Ways to Survive in a Ruined World. Sooyoung stops, as Sangah asks her if it wasn't the book the prophets call the Revelation. Sooyoung tries to deny the existence of the book, but Sangah then asks her if she had read it, which made Sooyoung reply that she didn't had to know. Sangah says that the constellations seemed to have no idea about the book. She asks Sooyoung if Kim Dokja had read it, since he knew information of the future, but Sooyoung only replies with a: "Who knows?" since she had to reduce the number of mouths as the information in the book was filtered but couldn't know how long it would continue.

Sooyoung turns her head when Sangah asks in a sad tone why he had done it. She then seems to know about the reason she had came. She stared quietly at her as it's reminded that Sangah used to be an ordinary office worker before the scenarios started, being in the same company as Kim Dokja. She then suddenly felt hot, and bursted out that she didn't know about him being whether dead or alive. Sangah denies this, as she knew he wasn't dead. Calmly, describes him being a different person from what she used to know when both were working together before. Sooyoung says that she still probably didn't know him well, to which Sangah answers that he was still himself, and ultimately tells her that she would go and rescue Kim Dokja. When Sooyoung is about to open her mouth after monologuing how Kim Dokja was lucky to have people worrying about him, the next scenario starts, leaving them having to work together once again. Sooyoung says that, even if both weren't colleagues, it was better than nothing. "Han Sooyoung tried hard to recall the contents of the original novel but no matter how she thought about it, a strategy didn’t pop up. Then the only way left was a full-scale battle. Fortunately, there was Yoo Sangah right next to her. They weren’t colleagues but it was better than nothing."

However, due to her lack of knowledgement about the book, she didn't know about a weakness to defeat the creature being faced. She eventually gets helped by the constellation Abyssal Black Flame Dragon, although surprised at first that he knew about the creature's weakness, since he didn't read the Three Ways of Survival at all, and asks about the one who leaked that information to him.

On another occasion, Sooyoung wakes up from a dream she's had as she notices she's lying on the couch. The dream itself had been repeating since a few days ago, and no matter how much she tried to interpret it, she couldn’t get a sense of the dream. She then hears a television on the background, as she rolls the ice on her mouth. She then notices and wonders about an ice cube being in her mouth, and asks Lee Sookyung about the reason of this. Sooyoung concludes it had been Yoo Sangah the one who had done it. She asks about Yoo Sangah after knowing she had been sleeping for two hours, and Sookyung tells her she was drinking coffee in the break room. Sooyoung numbingly asks about the break room, wondering if the place was a company. In fact though, they were in an abandoned company building. Heading to the place, she asks Yoo Sangah about what she was doing. She sees that Sangah was using one of her stigmas, asking Sangah if she was crazy, since she had used that stigma before. Sangah doesn't reply, so Sooyoung continues saying that she didn't know what could happen if she spammed that powerful stigma. The stigma itself was Hermes System of Olympus, Olympus' big data network that gained information from all over the Star Stream to measure the future. Sangah replies it couldn't had been helped, as the worst situation had to be avoided. Sooyoung asks about her not knowing information about the future, but Sangah replies back that her skill wasn't enough, as there were many variables.

The stigma itself, described by Sooyoung, shortens the user’s life span. Even aware of this, she was unable to dissuade Yoo Sangah because she played a large credit in the group members reaching the 45th scenario. If it wasn't for Sangah measuring future scenarios, the members from the company would’ve experienced a major crisis in the 35th scenario and 40th scenario. During the 3 years Kim Dokja had disappeared, it had already been a long time since the hope of him coming back had started to dim. Sangah looks at her coffee and recalls her days working at the company, adding that she always hid in the breaking room. Sooyoung says she didn't know as she didn't work in a company, and Sangah says back that she wasn't a company person as she smiled while Sooyoung licked her lips. Sooyoung asks about she and Dokja being close, Sangah only replies that even then, they were comrades. Disaster alerts were playing after their conversation, which announced the arrival of monsters in Busan.

When fighting Kim Namwoon as an Outer God, an explosion makes Han Sooyoung fly away, and in an attempt to minimise the the impact force, she shrinks herself but still was seriously injured. After Yoo Joonghyuk lures the Outer Gods from the companions, Yoo Sangah approaches Sooyoung as she asks if she was alright while coming closer and supporting her, getting a blood-vomiting from the woman while she tries to tell Great Sage, Hades, and Uriel to go after Yoo Joonghyuk. However due to using a power that went against the Probability, her incarnation body was being swept up in the storm of aftermaths, detecting a powerful force about to explode within herself. Upon noticing this, Han Sooyoung shouts out Sangah to get away, but she refuses by holding her shoulders ever tighter and shooking her head. The power inherited from Sakyamuni of Sangah was being transmitted by the contact on her shoulder. The heiress tells Sooyoung to fight [the force], reminding that she also fought it off and had survived in the past. Han Sooyoung only curses, and her consciousness began to fade away while her Fable continued to speak to her.

Although still not having a strong relationship as Han Sooyoung has with Kim Dokja, they are seen to being adapt to each other properly with the time, and eventually improving their bond to a friendly one, still having their disrupts but as companions instead of enemies, supporting each other when needed.

After Yoo Joonghyuk returned from space to spread the story to other timelines, Yoo Sangah, Sooyoung, and the rest of companions get notifications of Dokja's stories coming to his body in their world, which surprised Sooyoung as she believed that the Star Stream's system had been broken. Han Sooyoung calls out Sangah's name and she receives the signal, accelerating the vehicle they were in to Lee Seolhwa's hospital. Sangah tries to tell Sooyoung something, but her voice can not be heard due to the noises coming from the surroundings which were the notifications of Kim Dokja's stories coming back and ultimately reviving him. Along with Seolhwa, everyone hurry up to the room Kim Dokja was in, and when the door creaked noisily as it opened, Sooyoung is grinning like an idiot when she's reminded of the sentences she really wanted to write sometime, and so concluiding the story with it being for just that one reader.

In a side-story from around the time set in the 3 year period that Kim Dokja got sent to the 1863rd turn, Yoo Sangah is reminded of the old days after Sooyoung extinguishes her [Black Flame] by blowing her fists, she remembers the time when they didn't get along well at this time, to which Sooyoung asks if they still do now, to which Sangah replies that at least they "were not trying to kill each other" while brightly smiling, making Sooyoung streak her neck with a disgusted expression. Sangah confesses not being interested in saving Seoul, and instead of asking what did Sangah want, Sooyoung agrees by telling her she was going to help too. She asks what could she do for helping, and insists Sooyoung to let the incarnations escape, but she replies she can't do it alone. Sangah warns that if she kept pushing, both would be locked up, however the author replies that it was better than being locked up alone.

"The stigma Hermes Stigma dramatically shortens the user’s life span. Han Sooyoung was aware of this fact but she was unable to dissuade Yoo Sangah because Yoo Sangah played a large credit in the group members reaching the 45th scenario. If it wasn’t for Yoo Sangah measuring future scenarios, the party members would’ve experienced a major crisis in the 35th scenario and 40th scenario. Han Sooyoung bit her lips. This girl..."

Fanon
is one of the most popular ships within the fandom, being placed 2nd (without taking into account gen Joongdok) as the most favored pair on AO3. However, it's also a rarepair due of both not actually interacting for too long, at least not as much as other ships like HyunHee or even DokSang. The tropes between them, Enemies to Lovers and Girlboss x Girlboss, are very loved by fans, and since they're applied to the ship, it's popular in part because of it. In fan fictions, they're paired only as a minor couple, but still have their significant interactions. Both also can take initiative on the relationship, but Sangah is mostly better at it than Sooyoung in most cases, this latter being a disaster with a bitter-sweet-heart attitude and the former, functional, being sincere and courteous.

Another reason that might explain its popularity it's because of fans who prefer seeing Sooyoung with Sangah rather than with Dokja, as they see this later as her best friend. Not only that, but also Han Sooyoung tend to resemble lesbian women (short hair, tomboy-ish), and also canonically Han Sooyoung called Sangah's face refreshing and beautiful. This is why the ship tends to be paired along with Joongdok and HyunHee due to both being the female leads of the novel and webtoon, making it attractive to fans.

As said, it's a rarepair, but at the same time, the most popular ship depending on the region (eastern/western) fans are in. For example, SangSoo is known in the western, however it's not popular, though it's starting to gain attraction especially on Tik Tok. In the eastern it's known and popular due of the trope involving them (Enemies to Lovers, as mentioned). Although their interactions are really limited, there were people wondering how they were not a thing. A reason of why it's due to DokSoo having more development between characters and relationship rather than with SangSoo (Sangah's only gotten a character development during the Reincarnation Island arc). This is why, they prefer leaving SangSoo as platonic, but still enjoy the dynamic between them.

Even if most of the part of the fandom doesn't know the real reason about SangSoo being so popular, they respect others' opinions of this, as they don't seem to mind that much about it since Han Sooyoung isn't paired that much with other people aside from Yoo Joonghyuk and Kim Dokja. However, for some manhwa-only fans they seem not to understand the ship's origin, as Sangah and Sooyoung hated each other, but this had been corrected by novel and manhwa fans who explained their closeness inside the novel. They tend to be drawn very often together on Twitter on fan arts with sometimes involving JoongDok too. It's also fueled by the fact that canon art depicts both together too with friendly interactions. Their relationship is also developed even being minor in fan fictions, often supported by Kim Dokja whom Han Sooyoung shares a "mlm-wlw" solidarity with.

has 552+ works created on AO3 as romantic, 98+ as a background ship, and 64+ as gen respectively, being the most popular femslash ship on the fandom, and the third overall (second if excluiding gen Joonghyuk/Dokja).
