What Could Go Wrong? [Demonstuck] (DaveJohnKat aka CherryPepsiCola)

An rp I'm doing with some friends.
Your name is Dave Strider and you are 15 years old. You are also a demon from a very powerful demon family. You just started at your new school, Alternia High, after having to leave your last school due to certain, um, circumstances. You wear shades to hide your glowing red eyes and *excessive* amounts of cologne to mask your smell from demon hunters. On your first day at this new school, you already have a friend maybe a few, actually. The first person to be your friend is named John, he seems interesting enough, but his best friend, Karkat, intrigues you. You soon crushing on both.
Your name is John Egbert and you are 15 years old. It was supposed to be a normal day for you, but then the new kid came. At first you didn't want to bother him, but you soon decide to introduce yourself to Dave and become his friend for a number of reasons. You soon question whether it was a good idea or not. Your best friend is named Karkat, he is also someone you really like. You have other friends besides Karkat and you new friend (Dave) as well. However, when Rose first meets Dave, her first impression of him surprises you. Oh, did I mention you're a demon hunter from a family of hunters?
Your name is Karkat Vantas and you're 15 years old. You are a demon. You expected the day to be like any other day, but you were horribly mistaken when your best friend and long time crush, John, becomes friends with the new kid, Dave. You try to keep up your normal facade, but it soon becomes hard. Especially when you notice how close they're becoming in such little time. You're almost jealous of Dave, but you aren't really sure how to feel about him as a person. This becomes even harder over time. Unfortunately for you, John starts to notice how different you're acting and starts to get worry and ask questions. The only way to really explain how you feel to him would be by telling John how you feel, and there's no way you can do that.
