[He claimed that our initial night together was nothing out of the ordinary, mentioned he was tired of me, and even cheated on me with another girl—now that terrible ex continues to return to my life.] My ex-boyfriend resides next door. And he’s not just any ex—the cheating, completely trashy ex. “Girlfriend? We’ve been acquainted since our childhood, so I’m only dating her out of obligation. I’m kind of over her now.” Cheating wasn’t sufficient for him—he even spoke ill of me to his friends. There was absolutely no reason to stay with him. However, at a certain point, my ex began to behave quite oddly. He kept lingering around me, clinging to me in an infuriating manner and then… “I’m not just some guy next door. I’m the ex she was completely crazy about, the one she used to dote on and couldn’t get enough of.” He blurted that nonsense right in front of the first guy I’ve had feelings for in ages. What on earth is wrong with you, Kwon Doha? We’re no longer together!
