Yukio ?????

Nozomu's relationship with Yukio is hard to sum up. He both likes Yukio and often feels on edge, like he's the main character in a horror movie, around him. He greatly respects his art and truly believes in what he's doing... But also feels like he's going to get killed at some point. These feelings have intensified as Yukio tends to randomly show up in his apartment uninvited... And with no signs of entry.

Eiichi

Nozomu is the subject of Eiichi's one-sided hatred, and he doesn't quite understand it. He's tried many times to get Eiichi to grow up and act like an adult, but overall just tries to avoid him-- which becomes difficult when band activities are involved. He doesn't even think poorly of Eiichi despite it all, he's just tired of his childish nature.

Issei

Nozomu sees Issei as everything that's wrong with the music industry: a man who doesn't care about the art being made and instead tries to calculate how to get the most money out of everyone involved. He tries to avoid him, being disgusted by being around him.
