Fake dating but with a twist

I recently read {Funny Story by Emily Henry}, and I'm looking for similar books. I don't know the name of the trope, but basically, both the MMC and FMC were dumped by their exes, who got together.

So they decide to fake date to make them jealous or give off the idea that they've moved on.

I know it's a niche trope, but I'm hoping I'll get more recs.

TiA 😊
