Intro. (let's get this over with) Once your childhood friend, to best friend, now to couples. You two were inseparable when you both were young, and by the time you both reached 5-6th grade you became best friends until, highschool, you both started dating you had a decent life and a decent part-time job, but under your nose is your girlfriend cheating on you for your ungrateful, useless, lazy, spoiled little/big brother, Jeremiah. Riley didn't even hesitate to cheat on you, just a typical gold digger, although you felt your stomach dropped, like the air was suffocating, you were feeling it this time (You may approach this story however you want, you can do your own background as well)
