i don't remember the lyric or how it sounds like but there's a korean MV that i watched in my childhood that still stuck in my mind; two puppets on strings sitting far apart from each other, male and female. They were able to see each other but can't touch because their short strings prevent that from happening.
The puppets seem to be alive and connected to each other as i recalled them "communicate" with each other by writing a string of words on a piece of paper and swallowed it, the paper then will come out of the other puppet's mouth and that's how they've been communicating (my memory is vague but i think this is how it goes on)
then obviously they fell in love but knew no matter what, they can never touch each other (only looking from afar) thus they spread fire on their strings. They were able to touch each other but the fire spread to them. I think the MV ended with them melting in each other's embrace (like literally)
if you knew this MV please tell me
