@dauriru no, you see, the only progress is "are they together now or not", character growth is meaningless to the casual braindead romcom reader.
personally I think the Eve pick and everything surrounding it(not wanting to face his love for Ibusuki because he knows it'll "kill" Eve, in particular, is my favorite, along with her new resolution to make him realize it and to get rid of Eve, even if it's painful for her too) was a daring choice and really made the whole situation way more complicated, but in an intriguing, actually-not-hamfisted way.
Also, he doesn't deserve Ebino. But I do want her to be happy, because she is best girl, and because she is best girl, she can't win because that's against the laws of romance animes.
