Teen/School romance

The main reason I made this list. I just love both leads so much and how the couple embodies perfectly the concept of teen romance : dumb, playful and cute.

A love story where both leads find in each other a way to heal their own scars. All of this within a timeslip plot. 

It's nice

This one isn't really a romance, but almost (?

The thing is that you can clearly see how much both main characters care for each other even though they never really make it clear whether they are in love or not.

It's a short  one so It's perfect to watch when you don't have a lot of free time.  Also It's really well made cinematography wise!

I have nothing much to say I just really love Sejeong

Nam Onjo best girl.

The two main couples in this one don't end up that well, but there's a season 2 coming so that may change.
