Seeing Kohaku get a little jealous, even though he usually seems so calm, was super fun. Honestly, I’d feel exactly the same way as Yoi: having a handsome guy admit he’s jealous is a total cliché, but it makes your heart race like crazy. And I’ll say it again: I love the way they communicate! The fact that Kohaku is mature enough to acknowledge his jealousy really scores him major points. They’re reaching that stage where feelings are so intense that an almost instinctive need to "monopolize" the other person kicks in wanting their smiles, their attention, and their time all for yourself. It’s a very natural, real kind of selfishness when you’re falling deeply in love.
