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...?!
