Are you sure that this it not yaoi????

It's not a yaoi, it's a shounen ai as it does not actually contain sex.

well i think to it s shonen ai because all they do is kissing no sex with sex it would be yaoi Namine is right about that

am I the only one here that deems this series a true YAOI?
Murakami-sensei totally took this work to some other league and focused on comedy and characters' psychology instead of sex but they DO keep sexual relationship outside of panels
