Which Korean dramas' ost impressed you deeply?

I have seen many Korean dramas, and many of them have impressed me deeply. Let me introduce some songs that can make your ears pregnant!

First of all, I have to mention the OST in the most popular Korean drama "When You Sleep". I hear your voice, I will protect you, and the reason why the rosy clouds dissipate are very pleasant to listen to, especially when I see the background music played in a plot when I am chasing a drama. It really makes people feel immersive and brings the audience into the plot. I think the OST in it is very important for this play.

Another one is my favorite episode of Korean drama. This is the original audition for Kill Me, Heal Me. This song is really beautiful. The combination of rock and lyric makes people unable to extricate themselves. As a tone deaf person, I tried to learn this song, but I didn't learn it in the end. However, since I chased this drama, the audition is still the ringtone of my mobile phone.

There is also a musical-themed Korean drama "She Fell in Love with My Panic", starring Li Xianyu and the famous Korean female singer JOY. The OST "Never mind, I" in it has a brisk melody, which makes people feel relaxed and happy after listening to this song. It is because of this song that the hero and heroine in the play became attached and finally came together. They both like music. Of course, another OST in it is also very nice and interested friends.

I don't know if my friends who love watching Korean dramas feel the same way as I do: after watching a Korean drama, I will save the OST in it to my song list, and listen to it again every time I open it, and the plot in the drama will reappear in my mind.
