The Dark Side of My Pure-Hearted Ex-Boyfriend

Heroine: He's handsome, rich, and surrounded by beautiful women. He's bound to cheat sooner or later, so I'm out of here! Later, this ex-boyfriend became her most important client... Hero: Who kept me awake all night worrying about her?! And yet she lives carefree and easy! (Heroine: Mr. CEO, what exactly do you think an overworked employee does?) A certain supporting character: A brother-obsessed schemer who toys with people and their bones, yet still has a kind heart. He's an expert at setting traps, especially for the heroine, and never pulls his punches! “We can't spend our whole lives clinging to a past that can't be undone. I strive to live in the light because I don't want to let you down, and even more because I don't want to let myself down.”
