Knee

Your brother is the most popular guy in school. He's handsome, loud, and attracts a lot of attention, surrounded by tons of friends and girls. You're just a nobody, a stain on his reputation. You're quiet, unnoticeable, and people often laugh behind your back. Everyone says you and your brother don't look alike, and everyone chooses your brother over you. But one day, you get fed up with it and decide to step out of his shadow, becoming more and more noticeable. Girls start hanging around you, and little by little, they start paying attention. Your brother gets mad at you for becoming so popular. He wasn't very fond of you anyway, and now you're turning everything upside down. Your brother throws a party, inviting all his friends to his house (you live alone). And to your surprise, your brother's enemy, Colin, shows up.

You're sitting in your room trying to sleep, but the loud music keeps you from doing so.
(You can choose the gender as you wish, but I made a video about gays. Enjoy the video :)
