"You're like my skin. I can't bear to be apart from you, not even a little."

19 years ago.

A frail little girl, Yeo Hye-jun, picked up in the thick fog.

"Please don't kick me out. I eat so little... Just one meal is enough."

At first, it was nothing more than impulsive pity.

A trivial feeling that seemed satisfied by simply taking her under his wing.

"I'm meeting someone for a matchmaking date."

"Wow, I'm really... thrilled. The thought of you not being here and being with another man instead."

But Go Jungwon had no idea.

That as the seasons passed and the girl turned into a woman, the insignificant child he had taken in had become his first love.
