Kaoru's arc... This one is pretty interesting (better than the first episode of Haruka's arc) since our male lead is less mopey and going into areas that are questionable... The funniest parts is the scenes where Junchi thinks about what was going to happen to him in the back of the school with Kaoru and of course, Kaoru's waitress outfit that has a zettai ryouiki.
From what I seen, Kaoru is a tsundere and Junchi is going to have a fun time with her...
