My girlfriend, whom I cherished without having sex since we started dating, turned out to be a cheating bitch who easily succumbed to my handsome friend's advances. Natsuki Rin
After finally starting to date my childhood friend, she made a rare promise with me: "If you truly intend to cherish me forever, we won't have sex for one whole year." To her, intimacy should have meant something deeply special—yet ever since I introduced her to my handsome friend, she betrayed me without hesitation, turning into a shameless cheating slut. Though I'm shocked and heartbroken by her sudden change, I still feel somewhere deep inside that her true feelings for me might not have completely disappeared.
