You know that you're already settled to marry someone but you never told that to Sunoo.

Not until he found out, and thinks that you're cheating on him.

"You promise me, but you did not kept it..." Sunoo said

"I'm sorry..." You just said not even explaining

"I don't want to see you ever again.," Sunoo said then walked away, and you just watched him
