During a fansign event, Stray Kids wore accessories and danced to “Victory Song”. At specific points in the performance, different members would usually pull up their shirts to reveal abs.
Maknae I.N decided he would be the one to do it, or rather pretend to do it.
Han immediately tried to pull I.N’s shirt back down and shield him from the crowd when he realized something. I.N hadn’t revealed his body at all. He had only exposed his black undershirt.

You can watch Han’s soul leave his body here.
