ShiGuang

"Well done, new boy. We'll be partners in the future."

- Cheng Xiaoshi, to Lu Guang

ShiGuang is the slash ship between Cheng Xiaoshi and Lu Guang from the Link Click fandom.

Canon
Cheng Xiaoshi and Lu Guang are both the main characters of Link Click, with each of their own respective powers. Lu Guang can see anything that has happened in a photo within 12 hours of it being taken, and Cheng Xiaoshi can enter the body of the person who took the photo. By clapping their hands together, Cheng Xiaoshi enters the time of any specific photo that Lu Guang is holding. They have worked together for a while, and have formed a friendship that neither can deny.

Episode 1
The first episode begins with Lu Guang reminding Cheng Xiaoshi of the rules of going back into time. He gets to the third one before the dark-haired man cuts him off saying that he has already repeated it a thousand times. Cheng Xiaoshi extends his hand, and after a moment, Lu Guang claps down on it. Qiao Ling comes into the shop with a new order for the Studio, while Cheng Xiaoshi is playing on his phone and Lu Guang is cleaning their dishware. Lu Guang asks Qiao Ling for the pictures, and she happily complies with a pet name. Cheng Xiaoshi snickers, making fun of her before getting reprimanded. Lu Guang activates his ability on the photo; when finished, he looks up and tells Cheng Xiaoshi that they have a chance, but only one. At this, the black-haired man grimaces.

Cheng Xiaoshi is quickly transported into Emma's body. Lu Guang warns him not to be a drama queen, stops him from eating the spring rolls, and directs him to answer to Emma's boss politely. Exasperated, Cheng Xiaoshi answers in a falsely-cheerful tone instead, and then sarcastically asks Lu Guang if he was satisfied yet. The man just sighs and puts his head in his hands. With Lu Guang's instruction, Cheng Xiaoshi plays his part well and is safe from suspicion. They work together to finish the materials before 2:00 AM, and Emma goes back home. Her phone pings with a message, but he doesn't check it, per Lu Guang's orders. Emma falls asleep and has a dream about her parents, which morphs into Cheng Xiaoshi's parents, waking the time-jumper up. He tells a still-awake Lu Guang about his dream, who attempts to comfort him and have him go back to sleep. The two are lying down in different timelines, but facing each other. Cheng Xiaoshi ignores the rules and replies to the text Emma had gotten earlier.

The next morning, when Emma is in the meeting room, Mrs. Zhu bursts into the room and aggressively assaults Emma for cheating with her husband, while Cheng Xiaoshi can only stand still because Lu Guang told him not to interfere. After they've finished the dive, Cheng Xiaoshi returns and with the data, and they expose Quede Games's fraudulent crimes. Cheng Xiaoshi asks Lu Guang what he thinks Emma might be doing at that time. Lu Guang only replies that they should just leave the future be. On a news broadcast, Lu Guang sees a news report on Emma's death, but he doesn't inform Cheng Xiaoshi about it.

Episode 2
The Photo Studio is again tasked with a mission by Yu Xia, who wants to find the secret ingredient to a recipe that her friend had "stolen" from her in the past. Lu Guang receives a full envelope of photos, so Cheng Xiaoshi quickly jumps into the first one to where Yu Xia and Lin Zhen have just opened their new noodle shop.

Episodes 3, 4 & 5
With their new mission, Lu Guang shows Cheng Xiaoshi the photo they were assigned by a man named Chen Xiao and explains their motive. Though the black-haired man worries that the assignment may change the past, Lu Guang tells him not to worry and they dive.

In the photo, Cheng Xiaoshi accidentally takes a picture of the basketball court with his flash on, leading his captain to be distracted and be injured by the opposing team. Cheng Xiaoshi worriedly asks Lu Guang if he had changed the timeline, and Lu Guang replies frustratedly, that yes, he had. After a moment, he admits that the result didn't change, and that Cheng Xiaoshi didn't affect it too much. After quickly consulting an exasperated Lu Guang, he takes up one of their positions and play resumes.

When Chen Xiao makes his team's first point, Cheng Xiaoshi has a flashback where he invites Lu Guang to play basketball with him and his friends. He calls Lu Guang a newcomer, and compliments him on his skills. Lu Guang believes it to be no big deal, but Cheng Xiaoshi expresses his newfound trust in Lu Guang, as "partners". Back in the game, he apologizes to Lu Guang for being unable to lose the game, not even on purpose, even though the game was lost in the past. Lu Guang in the present can't do anything as Cheng Xiaoshi wins the game by just a point. Cheng Xiaoshi watches, horrified as the winning ball makes it's way into the hoop. While Chen Xiao's teammates congratulate him, the raven is frozen with the fear that he may have altered Lu Guang's time zone. Desperately, he calls for his guide, and when he doesn't receive a response the first time, lifts his hands to exit the photo. Just as he's about to leave, Lu Guang's voice appears again and tells him not to make such rash decisions. He defends himself by saying that he was just looking for the mission requirements, though Cheng Xiaoshi believes that Lu Guang was trying to teach him a lesson about changing the timeline.

Finally, after Chen Xiao has delivered all his words and has made it safely back home, Lu Guang tells Cheng Xiaoshi that it's okay for him to leave now. The photo-jumper decides to stay for one more meal, which Lu Guang grudgingly agrees to. In a stroke of bad luck, Cheng Xiaoshi looks at the calendar and realizes that the date of the past is May 12, the date of the Sichuan Earthquake. As Cheng Xiaoshi lost his parents to the earthquake when he was young, naturally, his trauma resurfaces and he attempts to warn everyone about it despite Lu Guang's reminders to not cause a scene. As a last-attempt effort, he begs Lu Guang if he can save just one person, Chen Xiao's mother. Lu Guang reluctantly accepts and tells him that they need to stay in the kitchen. Yet when the earthquake finally hits, Cheng Xiaoshi realizes it was all a lie. Chen Xiao didn't survive in the kitchen, he survived because his mother shielded him. Trapped underneath the rubble, Lu Guang commands Cheng Xiaoshi to leave the picture if the ordeal is too much for him, but he chooses to suffer along with her.

Cheng Xiaoshi exits the picture at last, while it is nighttime in the Photo Studio. Before Lu Guang can say anything, Cheng Xiaoshi punches him. No sooner does he collapses, sobbing over the deaths he couldn't prevent. Lu Guang bends down and embraces him, silently letting him vent his frustration. Independently, Cheng Xiaoshi makes the decision to temporarily stop the time agent business. Lu Guang complies, backing him up when Qiao Ling asks.

Episode 11
As Qiao Ling is talking about Cheng Xiaoshi's story, she recounts the day when Lu Guang miraculously entered their lives. Cheng Xiaoshi was painting the shop and just happened to meet Lu Guang, who was passing by. The raven invited him to help if he had any free time, and so Lu Guang was hence incorporated into their business. Cheng Xiaoshi as Xu Shanshan asks Qiao Ling if Lu Guang was attracted to Cheng Xiaoshi's beauty, although jokingly. In the story, Qiao Ling asks what Lu Guang is so attracted to in Cheng Xiaoshi, as he was the first friend that Cheng Xiaoshi had made beside herself. Lu Guang answers with an embarrassed tone, saying that it might've been because of his naivete. Cheng Xiaoshi laughs and it's evident to see Lu Guang's face turn pink while listening into their conversation.

As the night wears on, Lu Guang and Cheng Xiaoshi get ready for the attack. After being briefed on all the events, Cheng Xiaoshi asks Lu Guang if he can take the lead this one time. Cheng Xiaoshi successfully manages to trap the attacker in the darkroom, with the help of Lu Guang. Beforehand, the raven had told Lu Guang about his plan; how he was going to give the attacker clues and play a game. While Cheng Xiaoshi attacks the murderer with his ability, Lu Guang stands guard outside the door. When Cheng Xiaoshi finally obtains the murderer's confession, Lu Guang and the police burst through the door. Lu Guang helps his friend up by the shoulders and covers for him as well when the police question him.

Cheng Xiaoshi shows him the surveillance camera video for Emma, but Lu Guang is unable to find any hints. He claims that Emma's death was his own fault, so that he should be able to go back in time to fix it. Lu Guang agrees, and they clap.

The Daily Life in Lightime
Cheng Xiaoshi begins humming a song he heard from an ad constantly, causing Lu Guang and Qiao Ling to be relentlessly assaulted by the noise. Lu Guang is kept up all night from the sound of Cheng Xiaoshi's humming while asleep. The next day, he wakes up with bags under his eye and Qiao Ling asks him what's wrong. Lu Guang eventually starts bringing headphones to bed so that he isn't distracted by the sound anymore. Two weeks later, Cheng Xiaoshi has finally stopped humming at night. The subsequent night, it's instead Lu Guang who begins humming a song of his own. Lu Guang berates Cheng Xiaoshi for taking so long ordering takeout. Cheng Xiaoshi complains that he doesn't know whether or not a dish was good or not, and that he needed to check all the comments. Giving up, he suggests that Lu Guang use his ability to see whether or not a dish was good. Lu Guang reluctantly agrees, and activates his ability. After Qiao Ling comes to save them from their own demise, Lu Guang sheds a tear over the negative expressions while eating takeout. Cheng Xiaoshi smiles a bit at his show of emotion.

Cheng Xiaoshi finds a stray kitten loitering around the door of their Studio, so he brings it in to Lu Guang. Lu Guang regards it with skepticism, but allows him to keep it as long as no one is here to claim it. Cheng Xiaoshi prompts him to name the kitten, but Lu Guang tells him that there's no point in naming something that will leave quickly. The next day, Cheng Xiaoshi finds a collection of kitten-related care devices, but when he asks Lu Guang where they came from, the white-haired man feigns ignorance. As the days go on, the kitten grows extremely close to Lu Guang, leaving the raven to feel left out. Cheng Xiaoshi suggests that he be the one to clip the kitten's nails, but Lu Guang instead turns away from him and continues to care for the kitten himself. The existence of the cat is revealed to Qiao Ling, who excitedly asks if they've given it a name. Cheng Xiaoshi suggests that they name it Grenade, so he can yell "Here comes the Grenade!". Qiao ling suddenly receives a notification about a missing cat, to which everyone realizes they need to hand over their 'pet'. Lu Guang sulks after the cat leaves, so Cheng Xiaoshi attempts to comfort him by saying they could visit. Lu Guang quietly requests that they name it Elizabeth, getting the assent of Cheng Xiaoshi.

Lu Guang and Cheng Xiaoshi watch as Qiao Ling performs tarot. Cheng Xiaoshi views it as useless, but when asking Lu Guang for confirmation, the snow haired man tells him they should neither disregard it or believe it completely. Qiao Ling makes them both put their hands above each other on the deck of cards, and envision their future. Cheng Xiaoshi concentrates too hard that he ends up forcefully gripping Lu Guang's hand underneath his. Lu Guang tells him to be more gentle, and Cheng Xiaoshi apologizes for getting carried away. While Cheng Xiaoshi is frustrated over the Studio's lack of new customers, he tells Lu Guang that they need a handsome face for the cover of their Studio. Qiao Ling gives him her permission to advertise Lu Guang, so Cheng Xiaoshi jumps onto the seat next to him. Lu Guang is confused, asking him why he doesn't just publicize himself. Cheng Xiaoshi, delighted, asks if Lu Guang thinks he's handsome. Lu Guang panics and looks at him with a disgusted expression. Later, Cheng Xiaoshi is trying to get Lu Guang to pose for a photo shoot, directing where and what Lu Guang should be doing in order to capture his good-looking side. Though Qiao Ling is unsure if the photos will work, Cheng Xiaoshi seems confident in his abilities. Later at night, the trio goes back on their website to see extremely well-done pictures of Lu Guang posing. Qiao Ling exclaims in surprise, so Cheng Xiaoshi explains that he possessed Lu Guang's body in the pictures, gave him the right pose, and took a natural picture! Lu Guang, who sees the pictures as well, angrily leaves an anonymous hate comment, and shouts for Cheng Xiaoshi to quickly delete the photos.

The trio gets their filming equipment ready to stream. When Lu Guang is ready, he makes his way to the couch, telling Cheng Xiaoshi to scoot over. Cheng Xiaoshi tells him he has a large ass, which angers Lu Guang. Cheng Xiaoshi also acts exasperated when Lu Guang only delivers a few words to the audience. For their first question, Lu Guang explains that he sleeps on the top bunk only because Cheng Xiaoshi moves around a lot and creates noise. Qiao Ling says that she remembered Lu Guang telling her it was because he was worried Cheng Xiaoshi might fall. Hearing this, the raven gets up in Lu Guang's face, pleasantly surprised that he cares so much.

Fanon
Despite their contrasting personalities, Cheng Xiaoshi and Lu Guang typically get along well. They occasionally fight over small things, but it is mostly playful joking. Their characters and aesthetics draw similarities to other duos with black-and-white-hair; one person with a serious personality and another with a more carefree personality. The official artist of Link Click, INPLICK (@inplick) is known for some of her boys-love art, which often depicts a duo with black-and-white-hair who look very similar to ShiGuang, The artist has depicted Cheng Xiaoshi and Lu Guang touching hands and forming a heart together in official promotional art.

ShiGuang is the most popular ship in the Link Click fandom, and the ship has a decently big fanbase too. On AO3, it's the most written ship under the Link Click tag. With the events of Episode 11 though, HongShi has begun to emerge as a rival ship to ShiGuang. They are sometimes shipped with Qiao Ling in the poly ship, ShiGuangQiao.

The donghua itself has many ship tease moments, especially when they were forced to share ramen, and how Lu Guang hugged Cheng Xiaoshi (and bought him boba) even after the latter hit him in anger. Lu Guang also blushes occasionally when he's talking about Cheng Xiaoshi. Many fans love the ramen scene, because it sports many romantic undertones and leave a lot to fan interpretation. During a scene in "Emma", Cheng Xiaoshi and Lu Guang lie in alternate beds with the camera panning across both of them so it seems that they are together.
