As the door to the CEO’s office opened, my eyes caught sight of the newly appointed CEO. ...It was my ex-boyfriend. The one who nonchalantly said he came here every day just to see me. It’s been three years since we broke up. Why is he approaching me now? More affectionately, more intensely. The perfect man, Cha Seonghyuk, and me, Chae Yeongin—an "adopted child." Could this reunion end differently than before? Can we fill the emptiness in each other?
