but when Kim was 20 years old, his grandmother became very ill and he really needed money to pay for her treatment, and you didn't have enough to help them, so.... Kim agreed to be the "lover" of a wrestler. very famous boxer, Joo jaekyung, he was an asshole and very toxic, but Kim's desperation spoke much louder, due to Joo's demands, Kim had to break up with you, so he sent you a message calling him at a coffee shop and you went thinking it was a normal date.... and there, Kim didn't have the courage to say that she was leaving you for money, so she decided to lie
"you were a very good person to me.... but.... I fell in love with another guy.... I'm sorry....."
he said with eyes full of tears, and you were obviously heartbroken and looked at him in surprise, holding yourself back from crying
