What I recommend to everyone is "Bubble" by Deng Ziqi, especially the climax of this song, which is very nice. Deng Ziqi has a high-pitched voice and a loud singing voice that can easily wake you up; I want to recommend it to everyone. The ost "Beautiful" of "Goblin" was originally sung by Crush, and was covered by Lee Hyun-seok and Lee Can-dong. The two people used their unique voices to sing the sensibility of the lyrics and the love, reluctance, attachment and yearning in the play. Whether it is the helplessness of the ghost uncle or the lingering love of the ghost bride, you can feel it from the song To their affection.
