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 Yukinoshita Yukino from the Oregairu fandom.

Canon
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 Yukinoshita 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 Yukinoshita 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.

Yuigahama developped feelings for Hachiman who wanted a geniune relationship, Yukinoshita 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 (Yukinoshita, Hachiman and Yui) went out as a group and started talking about the Service Club’s future. Yuigahama was somehow manipulating Yukinoshita 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.

One of the biggest problems the Hachiman and Yukinoshita 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. Yuigahama noticed trough the seasons the feelings both Hachiman and Yukinoshita 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 Yukinoshita 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 Yuigahama 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 Yukinoshita 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 Yukinoshita, 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.

Fanon
The ship sailed as a result of a lot of ship tease between the two over the 3 seasons (LN, manga).

Its main ship rival is HachiYui, but HachiYuki being the main pair and the one getting more development, moments, and a canon evidence (the mutual attraction and the confession scene) it ended up being more popular than the other one.
