As we all know, this ends up being the recipe for eons of Aaaaaangst.
Dunno, it could also be the recipe for some comedy. That was my first reaction when the last page hit, honestly − that came so out of left field I almost spit my drink in laughter (with Akira’s face making it funnier).
Also, someone here said that Akira only liked Rin because of her superficial "mature" appearance, but I don’t quite think that’s the case. Sure, she has that cool beauty vibe, but much like Mayuki, Rin also has that clumsy side to her, and I think that’s part of what attracts Akira (hence the "Thank you Rin, for sucking at sports!") The "gap moe", if you will. X)
