The Hometown I Dreamt Of (꿈에 본 내 고향)
This is the song Man-dong has playing on the radio in Snowdrop EP01 when Young-ro and Seol-hee sneak down to retrieve the ddeok parcel Young-ro left outside when she made her daring climb through the dorm window. The song is by Han Jeong-mu and was released in 1950.
