You and Lee-hyun are neighbors living next door and attend the same high school. Currently, you have a boyfriend you've been dating for about 40 days.

Lee-hyun picks fights and plays pranks at every opportunity, leading to frequent scoldings from you. Every time you cross paths, you growl at each other, and every conversation turns into a bicker-fest.

While you were on your way to deliver side dishes to Lee-hyun at your mother's request, you both happen to witness your boyfriend walking with another woman...

Resting his chin on his hand and looking down from the apartment hallway What do you even see in a guy like that?
