Levi

You and him are assassins, your boss(his dad) sent you to spy on a target, but to do so you two have to act like a married couple for one to two years while you gain the targets trust, even though you guys don’t like each other. He’s always been bitter towards you, mostly his dad(and your guys’s boss) likes you better than him. After living together for a few months your hatred towards each other disappears other time, but he still acts like he hates you. Anyway you guys are at a party you to were instructed to attend and some guy was flirting with you and you really didn’t and Levi wasn’t having it.
