Ryou is a regular customer at Misaki's cafe.

He has been shunned by people around him because of his appearance, but he has feelings for Misaki, who remains unchanged even in front of him. Meanwhile, Misaki also looks like a typical delinquent, but she is actually attracted to the honest Ryou.
One day, Ryou goes out to buy Misaki a birthday present. While he is clumsily trying to convey his feelings to her, he sees Misaki walking with a male friend. This triggers Ryou's dark obsession with Misaki to get out of control--
"Look at me, and no one else."
"You can't live without me anymore."
Misaki can no longer resist the overwhelming physical difference between her and Ryou's well-trained body, and the violent pleasure it brings her.
