This is a long shot but I saw a tiktok ad for one of those Chinese shorts dramas where the male and female leads were the actors in a drama who fought like cat and dog off-screen, IIRC because he is a diva and she is over him, and then they're like... sort-of isekai'd into the drama they're acting in (but I think only sometimes? like sometimes they're in their normal world and other times they're actually in the drama world? it was a short ad and tiktok refreshed and I lost it without seeing the end I think) and it was so stupid but so funny T_T
I think like the whole thing is that they hate each other but when they're in the drama the story is forcing them together because they're meant to be playing lovers and it was so funny watching them acting like they wanted to not follow the script and the drama making them do it anyway.
Like I say, long shot since I can't remember much but I am dying to see how it went, it looked hilarious from the ad.
