Because My Ex Is Too Sexy

"I can't get an erection." Those were the blunt words uttered by my ex-boyfriend, Kim Do-jun, who suddenly reappeared four years after we broke up. With the same devastatingly handsome, sly face as before. To make matters worse, he showed up as a 5-billion-won investor who could save our company, so I couldn't just coldly turn him away. That was how it all began. "I'm not letting you go. If you can't be mine, I won't let anyone else have you." At work, we pretend to be nothing more than colleagues, but in secret, we share a covert intimate partnership. If I keep getting shaken by him crossing the line.. It's only because my ex is too sexy; that's all!.
