bp yj where all the members want to prank sb by hiding his lucky underwear but they don’t know where to hide it cause sb will find it anyway so they decide to hide it in yj’s pussy, they grab him, pull down his pants and underwear and stuff his pussy with sb’s underwear, when sb is back (from a shower idk) he starts searching for his underwear and can’t find it, he sees the members giggling and looking down at yj so sb starts to put his hands under yj’s clothes but still can’t find it and the others say “look better” and he strips yj down and opens yj’s folds and sees a peek of his underwear so he starts digging in yj’s pussy in front of everyone to get his underwear back (they’re not dating in this btw)
