Hi everyone!

The dramas I watch have mainly a good score, are very popular and are recent, so I wondered : "what if out there there are some really good kdramas that are underrated or have a low score AND I'M MISSING THEM??"

So I wanted to hear your opinion on kdramas (preferably rom-coms) that for some reason or another are not well known but you think that are really good!

Thank you! 

Heart to Heart was really cute
@Myauntmary  That's exactly the drama that I had in mind when i posted the question! It's one of my favourites but before watching it I didn't see it mentioned a lot!  
Capital Scandal
Cinderella and the Four Knights
Flower Boy Next Door
Tree Of Heaven
Time Between Dig and Wolf
One More Happy Ending
Falling For Innocence
Scholar Who Walks the Night
Time Slip Dr. Jin
Midas
Dear My Friends


Web Dramas:

Eating Existence
Love Cells
I definitely second Scholar Who Walks the Night!

I also suggest:

Bubblegum
Ex-Girlfriend Club
Marriage, Not Dating
It's a bit old, but I really liked Baby-faced Beauty
My Secret Hotel, Ruby Ruby Love, and To Be Continued are good
If My Runway is on Netflix in your region - you should check it out. I avoided it for a few weeks because I thought it would be really dumb but it was a nice short series that was warm and a little funny.
I second Thank You.
And Ex-Girlfriend Club, though it was cut, so be warned of a rushed ending.
I dunno how popular they are because they seem to be popular, but they're not spoken of much....
King2Hearts,
Good Doctor (just 'cause it's not on your list haha)
Producers (super niche though! I personally loved it.)
Beautiful Mind
Come Back Mister
Three Dads One Mom
and maybe Bride of the Century?
Thank you all for the comments: I've seen some of the series you mentioned, and I'll check out the others as soon as I finish Lucky Romance (which I'm loving!)
I'm Sorry I Love You
Love Shuffle
Love In the Forlorn City
