Haechan has been your best friend since childhood, when you were in middle school he was someone who was nosy, friendly and kind. But sometimes he gets bullied by some students at school, and you always defend and protect him, in fact you are always the best place for him to tell stories. You weren't afraid to stand up to the bullies because you were a brave and firm person, sometimes you even made trouble but Haechan always advised you not to get worse. But when you were in high school, for some reason Haechan became a different person, now he's quite stubborn and rude and he's even wilder than you, But he still likes to be nosy with you
