HachiYuki

"If I let you go, I won't be able to get a hold of you again."

- Hachiman to Yukinoshita

HachiYuki is the het ship between Hachiman Hikigaya and Yukino Yukinoshita from the Oregairu fandom.

Preludge
The two would have a one-sided interaction as Hachiman was involved in a car accident, as Hachiman was hit by Yukino's family's car when he saved Yui's dog. Thus making Hachiman miss the first week of his new High School life.

Season 1
After reading Hachiman's work about high school life. His homeroom teacher, Shizuka Hiratsuka did not like Hachiman's global idea about how he sees youth and typical high school life. As a sanction for giving her such an idiotic essay, his teacher decides he should join the Service Club to change his way of seeing high school life in such a stereotypical way, this is where he met Yukino, the top student in his grade, also portrayed as the prettiest girl in the school from Hachiman's POV.

At first Hachiman and Hachiman and Yukino both were considered as frenemies, they tended to insult each other in every possible way, calling each other by nicknames (YukiPedia, Fishigaya, Mr. Most Hated Guy In The Entire School, Seriousnoshita, Ice Cold Princess...) even though Hachiman only tried to befriend her after relating to her somehow due to their similarities, he forgot about this idea after being quickly shut down.

They somehow managed to become friends after a little while, also thanks to Yui Yuigahama who was desperately trying to both make them talk to break the awkwardness after she herself joined the Service Club.

Season 2
Yui developped feelings for Hachiman who wanted a geniune relationship, Yukino got aware of the situation after a while (being so-called a possible love triangle), her statement was then confirmed when all the service club members, (Yukino, Hachiman and Yui) went out as a group and started talking about the Service Club’s future. Yui was somehow manipulating Yukino while she indirectly said that she will be the one winning Hachiman over and keep him to herself, Hachiman did notice that and circumlocutorily did cut her off right away.

OVA 2
During the second OVA, after Hachiman and Iroha’s “date” at Chiba, the next day at the Service Club, Iroha showed Yui and Yukino some photos too and they stumble on the picture of Hachiman and Iroha on their “date” which Yukino would show him the photo much to his shock. Iroha would try to explain that she had Hachiman cooperate with her for the coverage and she later has the club help will out the coverage giving them a camera from the Student Council. Both Yui and Yukino would decide to go and look at Hachiman who decides to also come. On Hachiman's next free day at Chiba, he spots Yukino noticing that she was early. Although she states that it is normal to conduct in society by arriving 5 minutes early. Later Yui would arrive, and Hachiman would accompany them, they would first go to a shopping mall but because Hachiman was uncomfortable being around women's stores, Yukino appears before him stating that he’ll get reported if he does anything suspicious although he wouldn’t do anything suspicious. She’s not surprised by how he tries to avoid something. Although she wishes that he doesn’t perform anything embarrassing since he’s with them. He responds that he’ll be careful and tries to walk away but walking beside being near him and standing beside him. The pair goes awkwardly silent before Hachiman would asks about Yui and Yukino answers that she’s trying to check if they could publish the store of free newspapers. Hachiman would later notice that Yukino was looking at something but when he looks he sees that she was looking at a push-up bra much to her shock. She tried to leave wanting to know how Yui’s negotiation was going. Hachiman would think that Yukino still had hope, genetically due to her look at the bra. Later at a pet store, Yukino was meowing at a cat, and Hachiman would stand near due to her positioning. Hachiman notes that she loves cats but wishes that she would pay more attention to her surroundings. Hachiman and Yui and Yukino would go to a movie theater to watch a movie, they would later play ping-pong, and then they would eat at a diner. The next day at Service Club, they would give Iroha the photos they took and she would find a picture where of the three of them at Lix's cafe just like the one she and Hachiman took. After going threw the photos, Iroha wanted to take a photo of the Service Club and the members of the Club. But due to the arrangement of the members, Yukino was on the left side of Hachiman during the arrangement of the photo. Hachiman would try to get up but was stopped by Yui and Yukino, Yukino would state that Hachiman was being stubborn. Iroha would take a picture of the members of the service club.

Season 3
One of the biggest problems the Hachiman and Yukino were facing together with Yui was the fact that Hachiman and Yukino started feeling like they were in a co-dependent relationship with one another. Yui noticed through the seasons the feelings both Hachiman and Yukino held for each other but decided to ignore these signs to finally make her moves on Hachiman, getting her hopes up for nothing she indirectly got rejected, after trying to confess her feelings to him, Hachiman confirms his feelings for Yukino to Yuighama and asks her for advice. “I want to keep being involved with her” he says, he then accompanied her home and left a heartbroken Yui having lost all hope.

The major conflict of the last season then grew more intense as they both tried their hardest to push back against the idea and got each other as a result even more close. After lots of thinking, and a small discussion with his teacher Hiratsuka who is initially the reason Hachiman and Yukino met, he finally found the words he wanted to tell to her, Hachiman had enough of this co-dependency problem they were both facing and after returning home with Yukino, him and her had a deep conversation for the first real time in the season, because both were bluntly avoiding each other to forget about the feelings they were holding back. They afterward confessed their love to each other saying they want to devote their lives to one another from here on out. Whatever path the future holds for them, they want to be in each others life. They afterward became a de-facto couple, still leaving on their way some students suspicious about their relationship.
