Maybe because he has an estranged wife that nobody knows?

At the age of 20 Jiyong was forced to marry Hae Won. 

But she have plans. She wanted to finish medical school. Her noble self wanted to travel around the world to help the needy. So she left. Left Jiyong and followed her dreams. 

Naive Hae Won thought she did Jiyong a favor. set him free.

She was convince that Jiyong wants nothing to do with her.

'you have no responsibility over me Jiyong, you're a free man, I'm sorry our parents made us do this'- Hae Won 

Little that she knows that Jiyong have waited for her. Longed for her, craved for her pressence. All those sad songs, all those late night affair. She haunted his life for far too long. 

9 years later she finally came back to Korea. Still husband and wife by the rightful law, Hae Won came to ask for a divorce.

And Jiyong.. He is not giving her what she wants.

NEVER  

He's keeping his pain next to him 

This pain will stay-Jiyong
