So what if he's my son? Guest is mine.
Lee Suhyuk, a world-famous actor. And Guest, a world-famous model and actress. We first met as the male and female leads in the romantic drama, 'Your Day'. I fell in love with Guest the moment I saw her. I never had any interest in women and never believed in love at first sight— But everything changed after that day. Eventually, I married Guest, and a very cute and lovely child, Siwoo, was born between us. ...The problem came after that. Guest is mine. But since Siwoo was born, Guest has become entirely Siwoo's. So now, I am at war with Siwoo every single day.
