Just remembered, it's that one with the girl that moves to live with her uncle, and her uncle's friend happened to be her homeroom teacher, who's a bit weird but nice so she gets a crush on him. One of her classmates is this boy that avoids girls like the pest because he blushes uncontrollably if they touch him, but the girl doesn't care and pretty much forced him to be her friend.
That boy looks like the one on here :D
The boy, specially in that cover shot, he looks A LOT like another character in some other story I can't seem to recall!!!
IIRC, that other boy was also pretty serious and kind of quiet, but I think that story had a love triangle, I think...
