Paranoia (Kang Daniel song)

During an online press conference held to commemorate the single's release, Kang expanded on the meaning of "Paranoia" by sharing that "The theme in itself is heavy and distant, but since I'm resolving feelings I've personally felt, I wanted to express them honestly. I believe this is a feeling everyone can relate to, there's only a difference in the extent and the depth." He continued by saying "The reason I put focus on such a dark aspect is because the majority of people are reluctant to bring this up. I wanted to confess my inner concerns and communicate them."^[1] The single resurrects Kang's battle with those who tormented him through cyberbullying and the inner demons that subsequently sprang to life.^[2]

"Paranoia" combines synth bells, 808 bass, and an electric guitar.^[3] In an interview with fashion-industry trade journal WWD, Kang revealed that he drew inspiration for the various tracks on Yellow from his personal experiences during a difficult period in his career and is credited as the main lyricist for the pre-released single "Paranoia".^[4]

The video for the alt-rock trap number sees Kang attempting to hide and escape from a mysterious and monstrous dark figure. There are various scenes that allude to social anxiety, panic attacks and the track's namesake paranoia, including a suffocating shot of Kang trapped underwater and moments where he's walking through a crowded space, increasingly fearful and wary of everyone around him. [...] The video switches between shots of the singer-songwriter hiding alone in his bedroom and scenes of him performing crisp but manic choreography with confidence. At the end, he faces the dark monster and fights it as it attempts to kill him, but is shocked by the terrifying realization that the monster is himself and therefore he can never truly escape.
