Insanity.

"Yun Ki! Stop!" Areum shouts in the corridor. 

"Why, Areum? I told you I don't feel a thing for you! Take a hint, will you??" Yun Ki screams over his shoulder. 

Yun Ki opens the doors to his chamber, seating himself by the edge of his bed, followed in by Areum. 

"Why won't you give me a chance?" She begs. 

"Why won't you let me make you feel better, Yun Ki? Have you forgotten it all? Our chess nights, the way you wouldn't even let me sleep a wink until you --" 

"That's enough. You're crossing the line." Yun Ki roars, standing on his two feet. 

Areum stumbles back a little, almost as though she's woken a Lion from deep slumber.

"We never had any lines, between us...What's wrong with you?" She cries. 

"Areum, there was a line drawn between us the day I told you what I felt for Soojin."
