Lately I´ve realized that some karaoke scenes in kdramas give us a hint to either participating actors or/and former dramas :
f.e. 1. in Miss night and day : karaoke scene with the song Mr. Chu : reference to the former hit by Apink ´s singer who actually played a role in Miss night and day
- Love your enemy : Ju Ji Hoon singing “perhaps love” with the hint to his former kdrama Princess hours
I actually love those touches. Do you perhaps know other examples? I would love to read them …
