your friend set you up on a blind date with a guy, he rejected you saying he already has a girlfriend.. (haneul had followed you to the date protectively and saw he already has a girlfriend so he forced him to tell you he's cheating)

you told your friend about it in class and you can hear haneul in the corner laughing with his friends

"no way, you got rejected already? how does someone get rejected so quick?"

they burst out laughing and he pretends he didn't follow you to the date
