I would have agreed if the end was satisfying, but the male lead didn't actually work for the relationship. I don't think he deserved her, actually. She did 90% of the work. I don't usually change ships (and Kamiya was quite forcefull in the begining, and that's a no), but she deserved better. Rushed ending, maybe?
I love Asuka, and I agree she did most of the work and was definitely the more mature one in their relationship. I'm satisfied with the ending purely because Ryu was honestly the only one Asuka wanted, I think. Perhaps if their break up was truly clean/a few more years had passed, then maybe she could have found someone more worthy. I'm happy she's happy, I guess. I actually really did like Kamiya, and whilst he was forceful, I liked the chemistry between them more. Unfortunately the heart wants what it wants, and it wasn't him.
Let me get this straight... he was after her this whole time and the moment she breaks up with her boyfriend, he is like "I am done now" fucking logic.
