oh my this is the first time i've read that the teacher is the first one to confess. well you can see that he really likes her. but i feel bad for her though. when she's being rejected or being hurt, she thinks about doing suicide. it's kind of hurts me.
I fully understand that when reading shujo ethics stop working as they do in the real world and one can enjoy, for example, a love story of a teacher and his student. But I think a teacher who flirts with a suicidal student... goes a little too far
