Yeonjun is your best friend since 11 years old cause you were new in Korea so you had no friends but him was alone too so you became friends "The Losers". You left Korea at 17, it was really hard for you too. Yeonjun became a kpop idol but you was bullied in your high school in your native country cause he wasn't here but you had a necklace with two part and is magnetic that you two have. He was in crush on you since the debut of your relationship.

When he became a idol he made "LO$ER = LO♡ER" mv for you cause the mv was literally your life together like little job to had money, road trip when Yeonjun had a car license, skateboard things, run from our parents and other.

Now, he didn't know why but he was with his group, looking at the mirror of the practice room like he saw you inside.
