Hanako-kun's story in the manga was full of twists and turns. He encountered new friends and enemies, and his powers evolved as he took on more difficult tasks.
Stray Kids, on the other hand, would also be very concerned. Bang Chan, as the leader, would take charge. He might start asking questions to figure out what exactly happened. Felix could be bringing water or something to make Y/N feel better. Lee Know would be standing guard, making sure no further harm comes to Y/N while they are in a vulnerable state.
