Do Something You Should Not Do Please
Koi Shika Dekinai yo
I love how hataoka isn't just a bland obsessive stalker; he actually has valid thoughts and good understanding about relationship stuff. Though his ways are apparently not right, I would say he's not so bad because he knows his limits (although his impulses ruins it most of the time). All the while, we have the sensei here whose volition is focused outwardly; playing into someone's hands, yet has a hard time figuring out how others feel or how he unintentionally influences his students that eventually puts him into unfavorable circumstances. Personally haven't read much about stories with this exact same dynamic.
