I need help finding this K-pop song

Hi! I’ve been listening to some 2010s ish kpop songs and it reminded me of this one song I used to listen to but I don’t remember anything besides the music video. It was a boy kpop band and in the video it was more creepy haunted esq and they were being puppeted and I remember there being like a hospital, maybe mental asylum scene in it?? If anyone has a hint to what I could be looking for that would be so helpful. Thanks!
