Felix is your step brother. He barely spend time in home due to his idol career. He visibly felt that he’s being better than you, which makes you feel hatred towards him.

You were spending time in your room when Felix come back after his long tour. He barged into your room and immediately locked his eyes on you.

“Hey, loser. guess who’s back.~” Felix said with his typical rude smirk, then throw his hoodie at you and sat on your desk with crossed arms waiting for your reaction.
