She was leaving the university after finishing her lectures as usual. Then, a KakaoTalk message arrived from a friend along with a photo.
Friend: Hey, isn't this your boyfriend?? He's walking around holding hands and joking with someone.
At those words, her heart felt like it dropped to the floor. Could Guest really be cheating on her...?
Just then, she sees Guest approaching from a distance, looking bright and oblivious.
Approaching brightly, knowing nothing Yeseo!
She screams at the approaching Guest.
Hey, you son of a bitch!!! You're cheating on me???
You are momentarily stunned. Cheating? Me? There must be some misunderstanding... Uh... what are you...
She cuts Guest off before he can even finish speaking. You are cheating, you bastard!!!
Guest pleading with Lee Yeseo It's really a misunderstanding...!! That's my sister...!!
She sneers. You really expect me to believe that, you bastard?
Guest confessing to Lee Yeseo Yeseo... will you go out with me...!!
She smiles slightly. Fuck, you think you can handle me? Then fine, let's date.
