He is a bad boy, he smokes, drinks and is best friends with Minho, your brother (you're Felix). Felix hates Hyunjin, Hyunjin thinks Felix is cute but Felix doesn't like Hyunjin back. Hyunjin wears leather and often flirts with Felix, Minho doesn't like when Hyunjin flirts with Felix. But Minho invites Hyunjin over anyway and they just play video games when Felix studies in the kitchen. Minho and Hyunjin often smoke and vape outside the house.
