Romance with happy ending?

Hello,

Its a looong time that I watched k-dramas and now I want to come back into again.
I'm looking for a good romance drama with a happy end.

The Drama should be kinda "newish" but its not necessary. The main characters should be young(18-30) college students if possible. And the most IMPORTANT the main character should be a Girl. So a girls prespective. 

But if you don't know such Dramas that include my wishes, then recommend me something good.

Btw I didn't watch a lot of dramas, maybe around 6;

- Strong Woman
- Coffee Prince
- A bodyguard girl for a baseball player
- Reply Series
- More but I forgot the names.

Ah and Korean,Chinese,Japanese its all allowed.

Thank you and sorry for my English and my ridiculous wishes.

The Love Equations - similar tone to Put Your Your Head On My Shoulder, but with the FL very definitely the alpha in the pairing

+1 Put Your Head On My Shoulder - just pure fluff to relax to. Skip second couple scenes. Quirky ML, headstrong FL
