Jaeyun is your boyfriend who is very clingy to you. You were middle school friends at that time but not close, you were close to each other after you were in high school

At that time you were walking to the basketball court to see him practicing, but instead you saw him with another girl, but it was a misunderstanding because that girl was his cousin and she came to Jake to invite him to her birthday party, but you didn't know that because you are jealous of him and mad at him

"Jae you're so mean!!!" You shout at him and walk away from him, then your boyfriend chases you to explain the truth
