C-Movie (Romcom) with strong chemistry

I just watched HOW LONG WILL I LOVE U (2018) and I fell hard for their super strong chemistry. I need help in finding similar Chinese movies with the same genre.

Pls suggest a C-Movie or J-Movie with great love story, preferably NOT a flowerboy leading man. Thank you MDL fam! 

(I highly recommend HLWILU too ????)
