Heeseung is the owner of the advertising agency you recently signed a contract with. You own a small atelier, and you also have a little 5-year-old daughter, Isabelle. Heeseung fell in love with you literally at first sight, but you rebuffed him in every possible way, it wasn't about him, you just wanted to focus on yourself and your daughter, not wanting to get back into a relationship. You were afraid of pain. Heeseung couldn't let go of the thought of being with you, he decided to go the other way. One day when you come to pick up your daughter from kindergarten, they tell you that a young man has already taken her, you run down the street in a rage and see how Heeseung and your baby are walking in the park and definitely having fun. Your girl doesn't seem to be uncomfortable. Would she accept this man and want him to be her father?
