I will try to suggest 5 alternative titles to the multitude of gems you have already posted, they are among my favourites, even if they may not attract much attention
in my personal opinion these dramas are perfect examples of great screenwriting combined with outstanding acting performances by the entire cast in each of them
Call it love: What can I say? Healing can sometimes come from your worst enemy.
Lost: The last dialogue between the main couple is worth many rewatches where they each share about their affair just cause they only have each other to share it with.
Mouse: That damned second half. I felt as if the land under me was being snatched away little by little and before you realize you are drowned in quicksand
Have to mention 3 dramas here that depict the power of motherhood. Mother/Lie after Lie/Hi Bye, Mama!
Mr. Queen (This is a historical and comedy K-drama. Plus, I love the female lead, and she plays her role well.)
A Time Called You (If you enjoy time-travel K-dramas, this one's perfect for you. I watched it breathlessly until the end.)
The Light in Your Eyes (By the end of this K-drama, you realize that your youth was the best time of your life. If you're looking for a K-drama with surprises, I highly recommend it.)
Summer Strike (Sometimes, the monotonous life we live makes us forget how simple things can bring us joy. As you watch this K-drama, you'll slowly feel a sense of peace filling you.)
Goblin (It's that well-known K-drama from 2016(the best year for K-dramas). Even though everyone knows it, I still recommend it. It never gets old.)
