I usually don't cry while watching dramas (or movies), but some titles had me emotionally perturbed this year.
1. Dreamers (2018)
It's featured in KBS Drama Special 2018. This was a hard watch for me and all the surreal elements of the plot, probably done to detach the story, emphasized the loss even more.
2. Be Melodramatic (2019)
I started it last year but managed to finish only this year because I had the traumatic experience with the first episode which led me to stop it. The siblings' love and the healing was something.
