I'm guessing Kotani has some kind of trauma related to marriage... something like his parents' marriage was really bad and their divorce traumatized him so now he never wants to get married himself, which, okay, sure, but then he shouldn't have gotten involved with Shishikura's marriage interview/date thing with the nerd alpha in the first volume. Sure, he loves Shishikura and that's why he did it, but holy crap is it selfish to try and screw with someone else's chances for marriage, only to then go "oh yeah btw i'm never gonna marry u lol"
