キスよりも早く1 [Kisu Yorimo Hayaku 1] - Meca Tanaka

Unlike "Gokusen", where the relationship between a teacher and a student is sweet and, I don't know, more real and less sinful, in "Faster than a Kiss" the female student, Fumiko (age 16) gets married with her sensei (age 24)! She is homeless, with a baby brother, so of course the best option is to marry her teacher...

Not interested in reading any further. So yeah, maybe there is a mystery involving the sensei (his past, his true personality... how was he when he wasn't a teacher), and his friend is kind of funny, but I am against a marriage of a Professor to his 16-year-old student.
