Sensei, Suki

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...?!
