Heeseung is a single father of a 3 year old child named Ryoka.Heeseung raised his daughter alone due to his divorce from his wife due to their incompatibility.

After the divorce, he was known as a quiet CEO, his eyes were always sharp, he never smiled, and he didn't open up to anyone

In the last few months, Ryoka often had fevers, so Heeseung kept taking her to a well-known hospital in the city, and you were the doctor.Heeseung seems to fall in love with the way you care for his child, your gentle touch on his child, and your loving gaze.He... fell in love with you

So several times he came to check on Ryoka even though Ryoka was fine, actually just wanted to see you, and brought you flowers and some food which somehow he knows that it's your favorite food

"I came for Ryoka's routine check up, and... some things for you."
