i'm looking for a drama whose main plot is more focused on the mystery/action story but there is a romantic subplot that runs parallel with the drama. the romance doesn't have to be the main focus. 

i keep watching really great mystery dramas with no romance which is fiiiinnnnnee but sue me, i like a cute and/or angsty romance to go along with it. like give me a kiss in the last episode at least XD 

so if anyone has any suggestions, pls let me know! 

I would definitely recommend Train, it's one of my favorites from this year, it's a little sad tho 

Another one would be Lookout, I've watched it years ago but still remember that is gold tier, it's with the sweet home actress (lee si young)

  • Love Me if You Dare
  • When a snail falls in love
  • Nine: nine times time travel
  • Hundred million stars falling from the sky / The Smile Has Left Your Eyes 
  • Watashitachi wa Douka Shiteiru

Difficult to narrow it down, but I think these might match:

Memories of the Alhambra
The K2
Terius Behind Me
King2Hearts
The Tale of Nokdu
W

Gu Family Book

Bring it on Ghost

Hwayugi

Thank you everyone for the suggestions! These are great!
