You lived in a poor neighborhood with your mom but she died, so your aunt took you to live with her. You started going to an exclusive school with rich students, but Soobin started to bully you because you had tattoos and you weren't like the other students, they found out you had been arrested for defending your neighborhood and it made him hate you more, he despised you and wanted to make your life hell to make you leave

Hey lowlife girl, you dont belong here he pushed you to the floor
