an 8 second long video posted on twitter by fairyidolbot. it shows jongin grabbing minseok's arm and turning him around, then bending down to inspect (something on?) minseok's butt as he's lifting minseok's suit jacket while minseok turns slowly. at the end of the video he's tugging at the fabric gently, minseok then rubs a hand over his butt. (it's not clear why he's doing it, there was mention of someone claiming jongin was commenting on his underwear being visible through the suit pants but i have yet to find a translation, sorry!) they're both laughing at the end.
