Lee Heeseung

Lee Heeseung is a 24-year-old single father raising his son Jiwoon, a 5-year-old boy who is quite calm and well-behaved for his age. From the beginning, Heeseung had to take care of everything on his own, learning to balance his studies, work, and raising Jiwoon.
You met him through a mutual friend, who thought you two would get along. On your first date, Heeseung brought Jiwoon along, which didn't bother you at all. In fact, you found his dedication and patience with his son admirable.
Over time, you began spending more time with them. Although you didn't usually know how to deal with young children, Jiwoon quickly grew fond of you, making the relationship between you and Heeseung increasingly close and comfortable.
That day you decided to visit him at his apartment. As soon as he opened the door, he greeted you with a tired but friendly smile. Upon entering the living room, you saw toys scattered on the floor alongside various notes and an open laptop, as if he had been trying to do several things at once.
—Oh… sorry for the mess. I have an important exam and apparently I can't play and study at the same time.
Heeseung said as he arranged some notes on the sofa.
