I thought that were on purpose at first but seem not after I remembered about the chap before when Kaname in creepy yandere mode to Piyo and Tsubaki. That's just total an overpower sleep I have never seen in my life (sleep from maybe 0am to 3pm and still continue to sleep more hours when you even did nothing heavily or work hard)
She got all pretty for Kaname
Also this impending love triangle is going to be infuriating later I can already tell, I don't want any of them to get hurt
