Synopsis: My Trash Ex-Boyfriend

[He told me our first night together was nothing special, said he was tired of me, and even cheated with another girl—now that awful ex keeps coming back to me.] My ex-boyfriend lives next door. And not just any ex—the cheating, utterly trashy ex. “Girlfriend? We’ve known each other since we were kids, so I’m just dating her out of obligation. I’m kind of sick of her now.” Cheating wasn’t enough for him—he even badmouthed me to his friends. There was absolutely no reason not to break up with him. But at some point, my ex started acting really strange. He kept hovering around me, clinging to me so annoyingly and then… “I’m not just some guy next door. I’m the ex she was freaking crazy about, the one she used to hang all over and couldn’t get enough of.” He spewed that crap right in front of the first guy I’ve had a thing with in ages. What the hell is wrong with you, Kwon Doha? We’re broken up now! +
