Can anybody plz recommend me more dramas like "Hidden Love". It can be either Chinese or Korean. Thanks in advance.

My Fated Boy  
from the feels and essence literally the same drama. just ML in Hidden love becomes the FL and FL in Hidden love becomes the ML in my fated boy.

  • Go Ahead (ML has a lot of family trauma, and the two initially have a older brother and younger sister dynamic. However, they're closer in age, and the ML falls first.)
  • Flourish in Time (the leads have a non-related older brother and younger sister dynamic at the beginning, and the ML has a difficult homelife.)
  • First Love (the FL is very similar, imo, and it has the same kind of vibe, very soft)
  • Brother's Friend (FL has a crush on the slightly older best friend of her older brother who often hangs out at their house. There's a mini series and a movie to wrap up the story.)

Exclusive Fairytale- Leads had a brother/sister dynamic, but later fell for each other when they got older. In this case the ML fell first. They are also the same age.

Go Ahead +1 

Put Your Head on My Shoulder- This is a college/youth drama. It overall gives similar vibes. Both the MLs are respectful, but can get jealous too. 

You are Desire - This also a youth drama, and again, gives the same vibes, it's worth the watch.
