It's definitely cute! But this is one instance where I think a melodramatic third-act conflict would have actually helped the story instead of hindered it. D'Vaughn and Kris don't really grow to love each other like I prefer my fake dating, and instead are basically instantly into each other - even in the end

Kris reminds D'Vaughn of this when she says "see I wanted you from the start"

and since there's also basically no family drama, the road just like.... feels too smooth for me. Even when the families find out about the reality tv show, there's like, no reaction described except something like "people went wild".  I get the fantasy of everything wanting to be smooth sailing but I'm reading for the DRAMA!!

That's another thing tbh - if I see reality TV show I want reality TV drama, I want complex interpersonal relationships, and I want to be seeing other contestants too!! Like sure not their whole ass stories but a "x got paired with y" at the beginning, and the section starters with instructions for that week could have instead been a group progress meeting where everyone in the show talks about where they're at, and we get the drama of who's being eliminated (maybe with some "D'Vaughn and Kris, you really narrowly avoided elimination" drama early on that gets them to put their head in the game, and around THEN is when they're like hold on wait a minute...)
