Relationship with Producer: For Saki, who constantly forces herself to be the "perfect and invincible big sister" for Ume, the Producer has become her only shelter—the one person she can be a "normal girl" around, venting her weaknesses and acting spoiled. That sense of security eventually transformed into a special possessiveness and deep affection for the P.

She aims to be a top idol to break away from the self she hates and learn to love herself. Relationship with Producer: Though she was prickly at first, she soon realized she couldn't live without the P's presence. Between her intense jealousy toward other idols and the clumsy, vulnerable side she only shows to the P, her feelings have turned into a heavy possessiveness: "I want to give everything to this person and depend on them for the rest of my life."

For some reason, she's a bit uncomfortable around the Student Council President, Sena, who overestimates her. Relationship with Producer: Seeing the P work tirelessly for her sake, Kotone's feelings have clearly turned into a genuine crush (possessiveness). Aside from her desire to make fans happy, she has begun to direct intense affection toward the P with a straightforwardness rare even among the Gakumas cast, thinking, "I'm going to make the Producer the happiest man (or woman) in the world!"

Relationship with Producer: While Ume is usually innocent and cheerful, as her intimacy grows, a strong possessiveness takes root: "The Producer is 'my' Producer."
