Shitteru Yo.

From Shinmakoku Scanlations :
Instead of saying what he wants to say or do what he wants to do, Sawahata smiles to avoid getting involved. His school life seems so boring and nothing interests him anymore. Until he finds Hoshizaki glaring at him from across the classroom. The no-eyebrows-face intriques him, pulling at emotions he doesn’t know he has. What does Hoshizaki really want from him? And what should he do now that he can no longer avoid Hoshizaki?
