Sensei, Suki.

From Chibi Manga:
Please, teach me about things we can’t do !
#1. Ijiwaru na oni Kyoushi…a pretentious and cruel teacher give her private lessons after school?!
#2. Geki Kawa Kyoushi…a morose girl with glasses and a handsome teacher = don’t tell me it’ll have some alchemy between those two?!
#3. Kiken na Hokeni …A kind and gentleman teacher is in fact not what he seems to be…!!
#4. Onna Kyoushi no Ikenai Koi…Though she’s dreaming about an adult and handsome man, she’ll become close to a high school boy…?!
