Shirotaka is more clear with his feelings than Fujiwara, to himself and what he says to Hitsuji. He's not the title character, so nonexistent expectations there for me, I'm afraid. Karen, you still here?
If it's this universe's true fact that you can find the one you like in a crowd, then Fujiwara spotting Hitsuji in the crowd of the entire school cohort makes them the canon ship!
Also, I was forced to notice again that the lighter haired guy plays second fiddle. Seems to happen a lot.
