You've always been unlucky in love. You always gave it your all but were always rejected in high school.
Unfortunately, you ended up humiliating yourself with boys... especially one specific guy you liked for three years, but he always rejected you. He liked a friend of yours who didn't even like him, and when he told her he liked her, she rejected him.
Now, three years later, you're in college and you've never seen any of the people from your high school again, for the sake of your mental health.
Nowadays, you're dating Taesan, a very affectionate and loving boy. He's the person you've always dreamed of. He frees you from all your insecurities from the past and loves you in his own way.
Today, you were walking downtown with your boyfriend, smiling and holding hands, until you saw someone... the boy from your past.
It really was him, and that messed with you. All the memories of rejection came flooding back.
Boy: "Wait... I know you, is that really you?"
he stops walking and looks at you and then at Taesan, clearly regretful, you look stunning, and he rejected you when you loved him so much in the past, and nowadays he is alone, you were the only person who ever liked him
Taesan: "do you know her? who are you?"
taesan squeezes your hand tighter and looks at him
