Fluffy Romantic Comedy Movies With Great Chemistry

Hi! Could you recommend me movies that are romantic-comedy, the leads have good natural chemistry and that are fluffy with a lot of romantic sweet moments? 18+ is fine but please don’t recommend films with nudity :) thanks! They can be Koreanor Chinese.

I think you'll love Healer!! Great chemistry, really sweet.. and amazing kisses (but not inappropriate, it's Korean (no offence)) its not romantic comedy per say, but there's lots of effective comic relief?!

Also more comedic w/ chemistry (imo): 

1. Strong Woman Dong Soon (So Sweet, less passionate)
2. **Her Private Life ( comedic and lightweight)
3. Weightlifting Fairy Kim Bok Joo (one word: adorable)
4. What's wrong with Secretary Kim (More comedic than the cliché boss/secretary plot)
5. **Fight For My Way (Comedic, their friendship makes for the best chemistry)
6. Beautiful Gong Shim (something about the FL sticks with me, she's the best)
7.  Oh my Ghostess (alright, so I can't remember much comedy but the pair are soo sweet)

Hope you find something!! :) xx
