I wanted to dedicate my first time... to the person I've always had feelings for. That dream was... brutally stolen by Eita, the best friend of Mamoru, the person I like.

A stain on my life, a dark history... the biggest humiliation.

But during a camping trip during Golden Week, we began to share pleasure... and a change in romantic feelings emerged. When I'm feeling good and satisfied, there's no way I can't fall for Eita, whose lecherous face is always in front of me.

I know that Eita's true love is Ms. Miharu. That's why I can't confess. But... I want him to notice these feelings.

This work is a record of the beginning of a friends-with-benefits relationship... filled with painful unrequited love.
