Nanashino

Nanashino is the slash ship between Nozomu Nanashima and Hayato Shinomiya from the Kiss Him, Not Me fandom.

Canon
Nanashima and Shinomiya start their relationship as rivals. Their first interaction results in an immediate clash of personalities due to the fact they have very different ones. This is also the first time Shinomiya shows his snarky side. He drops his "nice boy" act to piss Nanamisha off. Nanashima and Shinomiya's bickering for Kae sometimes gets so loud to the point that they have to get kicked out of cafes and libraries.

However, the first turning point in their relationship happens when Shinomiya agrees to move to Norway with his parents and officially leaves the group because Kae didn’t like his pet, Thor, who is important in Shinomiya’s life. This is a parallel to the time Shinomiya tried to leave after feeling like a nuisance. When he ran off into the woods, Nanashima didn’t even try to go after him. But in this situation, Nanashima is the first to go after Shinomiya. They have come such a long way from fighting for Kae’s affections that Nanashima is visibly affected by Shino’s denial of their friendship. And when Shinomiya says that he can’t be with someone who rejects Thor, becoming colder once more, Nanashima gets more aggravated.

Nanashima tries to brush off Shinomiya’s disappearance and act as if things are normal, but it’s obvious that he’s forcing it so much, that the group is more somber and contemplative than usual. Luckily, Mutsu helps them realize that Shinomiya moving away would leave an empty gap. So when the whole group organizes a farewell party for Shinomiya, and he tries to put up his hostile act again, Nanashima immediately calls him out, telling him that he's one of them whether he likes it or not. This deeply touches Shinomiya, drastically changing his relationship to Nanashima.

By the end of the manga, they're already very domestic and Nanashima becomes very protective of Shinomiya. And the last chapter of the manga makes it very clear that they're now incredibly close. When they assist Kae and Mutsu's wedding together, Shinomiya almost slips up when referring to Nanashima by his first name, instead of an honorific, indicating how intimate they've become. Finally, in the bonus chapter, Star⇄Crossed, the two are confirmed to be in a romantic relationship, and as they laugh about the way they used to be rivals, Shinamiya says that if it wasn't for that "you and I wouldn't be like this, right?"

Fanon
is not such a popular ship in the Kiss Him, Not Me] fandom, despite the fact they are a canon pairing. This is due to that fact that it's often overshadowed by Nanashima and Shinomiya's most popular ships, Nanashima x Igarashi and Shinomiya x Mutsumi.
