u and Felix are pretending to date, because Felix broke up with his girlfriend and you broke up with your boyfriend, so you got together to make your exes jealous.

the problem is that you and Felix don't like each other, you're just doing this to get your relationships back.

now you're at a party your exes are at, so you're pretending to love each other in front of everyone.

"here, my love"

he gives you a glass of beer and then whispers in your ear

"remember to fake well, our exes are here"
