Koi Shika Dekinaiyo

High school teacher Umehara Akio drew Hataoka Kei, a problem child, out of his home and back to school. Years later, Umehara got transferred to a new high school and he met Kei again, who's now working as a delivery boy for a florist shop. Seeing his former student grown into a super good-looking college student, Umehara couldn't help feeling proud. What he didn't realize is Kei’s true colors… a pervert who molests his drunken, unsuspecting Umehara-sensei!
