"Hi Ren" is a musical exploration of a person’s inner struggle against their own darker impulses, personified as the character Ren. The song unfolds through a series of verses where the speaker attempts to separate himself from Ren, who represents his destructive, self-critical, and ego-driven tendencies. The speaker seeks distance from Ren, recognizing that his presence hinders his progress and potential. The song culminates in a powerful bridge where the speaker acknowledges the destructive nature of Ren, recognizing him as the embodiment of chaos, temptation, and even evil. Yet, the speaker also recognizes that Ren is an integral part of himself, representing his human flaws and capacity for both darkness and light. Ultimately, the song posits that the true struggle is not a battle to be won, but a dance to be mastered, one that requires self-acceptance and embracing the duality of human nature.
