Lol, when Miel does she should be manly and surprise him. Like if they were alone they could be talking and right when they're laughing Miel should suddenly say:"....I like you too." Then look down before blushing. (Don't ask, even I don't get how this is manly ╮( ̄▽ ̄)╭ )
Tsuji-sempai is adorable. Go confess, Miel.
