Ryou is a regular at Misaki's café.
People have shunned him because of how he looks, but he's got a thing for Misaki, who doesn't seem to mind that about him. Meanwhile, Misaki also looks like a typical delinquent, but she's actually attracted to the honest Ryou.
One day, Ryou goes out to buy her a birthday present, but he's pretty clumsy and can't really express his feelings to her. Then he sees Misaki with a guy friend, and that causes Ryo's dark obsession with Misaki to spiral out of control...
"Look at me, and no one else."
"You can't live apart from me anymore."
Misaki can't resist the overwhelming physical difference between her and Ryou's well-trained body, and the violent pleasure it brings upon her.
