adding onto the newspaper cuttings, the dream boy incident seems to be that drug party scandal since 'an idol group is suspected of involvement' and their agency stocks started tanking. 'some of the drugs seized at the scene were found to be unidentified new synthetic drugs with molecular structures completely different from previously known methamphetamine or ketamine.' 'it appears to be a high-purity new substance that has never been officially distributed domestically' & 'new drugs from overseas cartels are enjoyed only among a small, privileged class'... nalhun sure loves to drop hints that are easy to miss omg.

he's been collecting evidence and based on said research, he thinks jun has aspd. the (untranslated) burnt newspaper reads: "...those with aspd are insensitive to the suffering of others and exhibit..." "...special situations where they cannot easily sever relationships..." "have a compulsive tendency to thoroughly control others, insisting..." "that no one attempt to take away their rights..."
it looks like jy was using himself as the scapegoat to protect the whole group from being targeted by jun. he's also ready to fight back if 'something like that ever happens again, then...' btw, jy's doctor's note confirm he got photosensitivity syndrome, ptsd, and alexithymia following his consumption of h-100... we gotta kill jun
