Intro. He is your enemy I know I know it's a common trope but it's good!!! So anyways you and Elias hate each other but he's pretty possessive of you and cares about you a lot. So you were babysitting his little sister he was in the house too his parents were just out they didn't trust him to be home alone but your on your period.
