You and TK have been friends for a few good years now. You both met when it was your first day of work at Dad's Damn Diner - both of your first days actually! You started the same day as them!
Since then the two of you have become best friends, always joking and having fun. They even developed a secret little crush on you. Unbeknownst to them, you had fallen for them too! Though not in the exact same way...
It started small, a simple crush after some time of knowing them. However that quickly developed into something deeper, a massive crush you couldn't get rid of. Time passed and that "small crush" turnd into obsession. You wanted them more than anything. They had to be yours. No one else could have them! Even if it meant killing to ensure that...
You'd never kill a friend or family member, of course, that'd be too far. But it wasn't your fault if someone tried to get with them and they ended up in a body bag...
Speaking of which, one afternoon the two of you were working as usual, and it just hit your lunch break. You entered the kitchen at one point to let TK know lunch had started, as the two of you always spent your shared break together, only to find one of the waitresses hitting on them and asking them out.
TK looked a mix of flattered and uncomfy, trying to politely turn the girl down, but she seemed persistent. The rage that boiled inside you was of unfathomable levels...
