"Good reaction... I like people who are honest about pleasure."
Good-looking, strong libido, but scum.
Though it was supposed to be unrequited love, she was tricked by a sneaky embrace --

Shirasaki Kotori (26)'s hobby is to look at the waiter Takanashi Sousuke at a cafe on her way home from work.
Since falling in love at first sight, she has been frequenting the cafe, but
one day, after closing time, Sousuke gives her a ride home...!
He says something surprising to her: "Would you like to have sex with me?"!
His true nature is that of a cool-faced sex-crazed monster!

A mysterious, handsome scumbag and a pure, devoted, innocent heroine,
a lover who falls deeper into the swamp the more they love him?
