Carefree airheaded girl x obsessive boy. Iroha has never tried falling in love before. Suddenly she begins dating Kusakabe who is very experienced with relationships. However he has a habit of being overly devoted to and possessive of his girlfriend to the point where he becomes obsessive (and a little yandere). There are lots of funny and cute moments as the relationship of these two develops. I'm not a big fan of Kusakabe and the "possessive boyfriend" trope. He reminds me of the boyfriend of one of my friends from middle school, and he was a controlling asshole who tried to pull her away from her friends... I like Iroha, though. She's innocent and air-headed, but she still knows how to speak up and say no. Though I think she's a bit too lenient with Kusakabe.
