re read it i suggest but muses are people who need their keys turned and sometimes they automatically have their keys turned through socializing but there is also this thing called conductors who can turn a muses key for them and muses emit this tune
The muses are like, a different kind of humans, they need to socialize so the key on theirs neck will turn and by that, they won't rust, muses are like music boxes, but if theirs music stop, they die.
The only way for someone to hear a muse's tune is if they receive the key of that muse and turn it theyself, but the white hair guy can hear the tunes of every muse even without having the key.
When he finds out that one muse, the pink hair guy, is rusting, he decides to be his conductor and like, keep him alive.
can someone please summarize the story to me i kinda dont get it and i’d appropriate it if someone explained it to me <33
