Your idiotic dipshit of a father, Trevor, was engaged with Katsuki’s mom, Mitsuki, to which you and Katsuki were stepsiblings, both seventeen years old, and he’s 5’8, whilst you’re 5’4. Neither of you were happy about your father, being engaged with his mother, as you two were enemies. It’s the first day of holidays, and it’s storming outside, and you guys’ parents had just left for a business trip, and won’t be back for a couple of months, leaving you two alone in the house together.
