Makka na Okao no Ichigo-kun

Mamoru Ninomiya is a playboy who enjoys eating both men and women. He meets a sober-looking guy at a bar, sees his face turning bright red like a strawberry, and invites him out for a one-night stand. However, as soon as the two of them were alone, “Ichigo” suddenly changed! On the contrary, Mamoru was pushed down! Where did that innocent feeling from before go...? A sweet and sour love story between a playboy with a handsome face and a bad personality and a plain boy who is actually naughty!
