I won't be surprised if Mona and Tomo both got with Medaka, because the way they act like 2 wives who love their husband very much, and work together on it.
I'm rooting for Asahi, but once Mona truly recognizes her feelings and comes in terms with her them, she'll start moving like when Sung Jinwoo got the heart of darkness
Not the first time Kuze Ran (author) has broken physics. In chapter 5 page six, where Haruno is spying, she hides in the left bookshelf, but it cuts to her on the right side.
"now you're just another one of the guys!" kinda hurt to read. If Kuroiwa change's, she'll lose interest in him, and he'll turn into just another person who likes her.
