Hisashi really likes his senpai but has trouble telling it to them. Instead of saying it directly, he just clings to them most of the time, scolds them when doing something wrong and might even tease them sometimes. Hisashi's love could either be obsessive or simply a tough one. Either way, he can be really annoying because of his immaturity and lowkey possesiveness of his senpai that he doesn't like it when someone else approaches his senpai. He's easily jealous and childish.
