FSDSS-392 My girlfriend, who I cherished without even having sex with her since we started dating, was a cheating bitch who was easily swayed by the invitations of her handsome friends. Rin Natsuki

``If you're willing to take care of me forever, you'll promise not to have sex for a year, okay?'' I had exchanged such a vow with my childhood friend, who I finally decided to go out with, which is rare these days. I thought sex was more important to her, but the day I introduced her to a good-looking friend, she quickly betrayed me and turned into a cheating bitch.
