What happened to the little gloomy sound that was also on it?

No puedo creer que lo subieron, he tenido esta melodia en mi cabeza por meses, la escena donde muere chun ae me llego al corazón, me encanta esa serie, llena de pobres almas en desgracia, me da tristeza porque hay gente que en todo su camino no consiguen un instante de felicidad

we want to know the name of the ost!

Where can I find the ost? 😢

아니 이런거 어디서 들어 나 이런거 찾고 있단 말이야!!!!!

Can anyone tell me what is the title of this song...???

Who's the composer of the tracks?
