Han Sun-yul has long been scarred by a scandal involving her college sweetheart, Yoo Shin.
After eight years, he reappeared in front of her, leaving nothing but shameful rumors and resentment for Yoo Shin, who evaporated in an instant.

“What?”
“You had that look on your face.”

“He's worse than you can imagine. He'll only hurt you.”
Sun-yeon can't understand why he's so intent on her boyfriend, Ki-chul.
But she soon realizes that there's something between Yoo Shin and Ki-chul that she doesn't understand...
