ChiHaya

ChiHaya is the het ship between Ryūnosuke Chiba and Rinka Hayami from the Assassination Classroom fandom.

Canon
Chiba and Hayami have a steady friendship and are proven to have romantic feelings for one another. The two have gone on dates too. But they always ended awkwardly, since neither could hold up a conversation for very long.

Chiba is the best shooter in the class, with Hayami being a close second. The two were paired together with the task of shooting Korosensei while he was pinned down by the other students. They were paired together again in Korosensei's Assassination Test of Courage. In the guidebook, it's said that they both talk more if they're talking to one another, likely because they feel that the other understands them better than other people. The two are known in the class as the gunmen and for being calm and quiet.

They worked together in Civil War and scored their first kill. Hayami and Chiba celebrate by knocking their elbows and smiling at each other. They are seen at a festival together along with Hiroto Maehara and Yuuma Isogai. They are smiling again, which is, as stated before, a rare occurrence for both characters.

After graduation, Hayami helped Chiba set up his own architect business and the two are still friends.

Fanon
ChiHaya is a decently popular pairing among the fandom. It is the most popular ship for both characters. Hayami and Chiba are the only ones who understand each other and confide in each other whenever feeling stressed, when normally they would just hide those emotions. Furthermore, they have a great deal of respect for each other. This is commonly expressed platonically. However, it is unclear if it is extended romantically. Both are known to be calm, stoic and professional, but have a soft side.
