It's obvious that Wakano knocking Hanami down is just a ruse to get the readers to think Wakano actually has a chance and build up hype, but its clear Hanami will come out on top.
97 chapters for the first romantic rival isn't too early. Well she come up front and honest about her feelings to her rival. That's commendable and dangerous. But I also believe she doesn't have a chance and is only in the story to stir things up next school year.
@gigagiga Wakano is already someone's rival. Satoru's big sister. I could see those two trying to out do each other with sisterly affection towards him if all three of them were ever in the same room again during the present. I think we've only seen all three of them together in the flashbacks.
Predictable about lil sis... but shes out without ever having a chance.
Also predictable Wakano would give some trouble to Hanami... but unfortunately i cant see the big rival go down so soon.
