Childhood friends Naru and Kyoya meet again after working at the same company by chance.
The two become friends again, but Naru is worried because she can't confess her love for Kyoya.

One day, the two go out drinking after work.
Naru tells Kyoya that a colleague suddenly confessed to her, but Kyoya doesn't seem to care at all...?
She drinks too much to forget the shock and is taken to Kyoya's house.

"Any other man... I can't forgive that..."
"I don't want to be taken by that man..."

Kyoya actually has feelings for Naru, but
Kyoya, driven mad by jealousy, plays with Naru's unconscious body.
