The name of this song is the song of Paradise Island. This song is the theme song of "Beauty is a curse" in Detective Star. This song is more like whispering in your ear: hey, I found you, don't hide, you can't escape. This feeling is even scarier than scary nursery rhymes, totally different.
The original song is "Hide and Seek", which is obviously playful and a bit scary. As a result, the "talent scout" was changed to the version that everyone heard in the program now, and the program was probably a cover version of the lyrics.
Excerpts from lyrics:
Ding-dong, I have a secret to tell you quietly Welcome to the entrance to heaven. Ding-dong, someone is ringing the doorbell. Who treats pranks as games outside? Listen, who is crying, look, who is whispering. There are eyes outside the window. They have been watching you.
