This particular exchange when Bong-hee gets dumped by Jinho, Kyushik tries to explain to her that she kissed him while drunk, getting him in trouble. It was hilarious.
"Do you have any idea how much trouble you got me in?"
"What are you talking about?" Bong-hee walks away but Kyushik jumps in front of her.
"-This morning what?"
Kyushik gestures, pointing to her and then pointing to himself, as if saying, "You kissed me."
Bong-hee gestures to him and to herself. "You kissed me?" Kyushik shakes his head and repeats his gesture, and then Bong-hee smacks him in the head with her purse.
