Today, I learned the chorus of Wings by PIXY, probably one of the hardest dances I've actually tried to learn. It took so much energy and it took like 2 and a half hours to get down some of the moves, excluding the smaller details
Adios by EVERGLOW as I learnt it over a year ago but still struggle with the majority of the moves. And ICY by ITZY I can now do with ease but learning it took about a year and a half of several failed attempts
