Name of the drama please!

I don't remember the exact details but please help if you remember the drama. I've been struggling to find the drama name for a long time.

ML or FL I don't remember exactly but whenever they meet up one always sleep. The other get kinda annoyed after few times. But soon after the sleepy one thanks the other for always letting her/him sleep.

That sounds like the scene of one of the last episodes from "Marriage not dating"

Do you remember any actors or what genre? 

 Snowflake:

I found it after fanitha's reply. It's 14th episode of Marriage not dating. :) 

Ok.... It sounded like a shiw I watched but I  never watched that show
