Synopsis: The Secret to Winning Over Unrequited Love

High school graduation. The rival I’d been tangled up with all throughout my school years came up to me and confessed that he liked me. It wasn’t the outcome I’d imagined, but in the end, I thought I’d finally won. At least, until I ran into him again years later—this time with a young son in tow. Filthy slut… If your heart was that easy to sway, why’d you even confess to me in the first place? Well, whatever. Someone like you? Fucking you again would be nothing at all. Original Webtoon
