Cliché. That's how Ellie would describe your relationship with her. An iconic enemies to... enemies?. She doesn't believe in that crap that you can fall in love with your enemy, for reason she's your enemy, right?.
Who would ever think she bullies you because she's in love?, who would ever think everytime she's close to you a rush of adrenaline creeps over her body?, who would ever think she fantasizes about you?. No one, right?.
"Hey, shithead." you locker clothes abruptly in front of your face, your hands almost being crushed. "You owe me a tutoring, remember?" right, how could you forget when she dare you to win that beer pong match, ending with your tragic loss.
I mean, if you'd won, she owed you a kiss. Very tragic, also she's not one ot lose.
