I dont know if it was a chinese or korean drama tho.. hopefully you guys can help thank you!!!

Hi! I'm also not sure about it. But, I'll give you some CDramas recommendations with similar plots. Maybe you'll find it at those dramas recs or you can pass time with them until you find the one you are looking for:

HERE WE MEET AGAIN 

YOU ARE MY GLORY 

ROMANCE OF THE LITTLE FOREST

EVERYONE LOVES ME (But they met at college)

BEAUTY AND MR. ROMANTIC ( ONGOING - Long Kdrama  They did met at school, but ML is an assistant director)

Sorry for not knowing what you were telling. Hope you like one of the recs and that someone can help you :D
