I'm obsessed. I wanna keep reading this over and over, it's sooo cute!! But I love a good "Opposites attract" kinda story, like Ore Monogatari (very similar to this: Scary guy/Cute girl), Kijima-Kun (Scary looking guy/Popular good-looking guy. Yaoi and explicit) or Horimiya ("nerdy" looking loner guy/popular-ish assertive chick. Ps. I am in love with Miyamura Izumi).
I will probably read this 100 times, not gonna lie. I just finished it and I already think I wanna read it again...
