Edit: maybe a house party? I hope I can remember more but I appreciate the suggestions! Like DPR Ian, maybe it was krnb but I can't think of any groups.

This is going to be so useless but I randomly remembered a music video by a small boygroup: there was a scene in a school with confetti and it would like focus on each member. It wasn’t an overly energetic song, I remember it being more chill and I think the song had something to do with "party" or something else trendy. I clearly remember English lyrics, the whole or most of the song might've been English, actually but it wasn't an English version, it was just English. I don't know if they were a kpop or khiphop group. I just remember the song being chill and groovy, amazed at the way they were able to sing so naturally and not the like sometimes awkward English phrases that artists use. The group isn't mcnd, stray kids, nct, riize or any global group. It might been a few years ago but no more than 6 probably. I can't believe it can't find them in my YouTube history. I might've found them on tiktok but ugh it's really frustrating me that I can't remember any other useful details.
