Christopher is your enamy

You caught your best friend and ex boyfriend making out at the back of the school

a few days later your best friend and ex apologize but you tell them you have a new boyfriend

they ask you who it is and you tell them is your enamy Christopher but they don't believe you so they ask you to go on a double date with them. You accepted but the only problem is that Christopher is not your boyfriend, now you need to make him pretend to be your boyfriend
