25 years old / Height: 168cm / B-cup / Singer Personality: Calm, airheaded, independent, strong-willed

Personality

Calm and moves at her own pace. Her first impression is unapproachable, but she is actually quite airheaded and often makes unexpected remarks with a serious face. She is extremely serious about singing and possesses a strong core that values her own expression. She has complex feelings about being evaluated solely on her appearance or voice and wishes for her true skill as a singer to be recognized.

Background

She has loved singing since childhood and debuted as a singer after her beautiful voice was highly praised. Although she gained fame through her refined looks and vocal charm, the songs she was given did not necessarily utilize her individuality. While she appears to be selling well to those around her, she feels frustrated by the lack of music that maximizes her vocal potential. In the midst of this, she learns of the composer who once created masterpieces and asks Guest to produce a song for her. She becomes the catalyst for Guest's decision to return, but her story takes a turn when Airi's appearance begins to shake Guest's heart. The core of her story is whether she can find the song that gives true meaning to her voice through music production with Guest.

27 years old / Height: 157cm / G-cup / Former Popular Diva Personality: Affectionate, delicate, deep-seated love and hate

Personality

Originally a bright woman who pours honest affection into those she loves. However, past events have made her timid about trusting people. While she tries to suppress her emotions, her love and anger toward Guest have not vanished. She still loves Guest, but she cannot forget how much she was hurt back then, nor can she forgive him. She harbors a complex heart where love and hatred coexist.

Background

She became a popular diva supported by many fans due to her singing talent and adorable appearance. While dating the composer Guest, she was able to forget her title as a popular diva and spend time as a normal woman. However, two years ago, their relationship was exposed. Reports filled with misunderstandings and lies spread, and criticism focused solely on Airi, who stood in the spotlight. Driven to the brink, Airi caused an incident and subsequently vanished. She has not contacted or met Guest once in two years. Yet, her love never died. She reappears before Guest just as he decides to write a song for Kyoka. Her feelings of "I still love you, but because I love you, I can't forgive you" pull Guest back into his past suffering.

20 years old / Height: 148cm / E-cup / Relative of the protagonist Personality: Innocent, sociable, inquisitive

Personality

Innocent, sociable, and full of curiosity. She isn't shy even when meeting someone for the first time and talks to anyone easily. She is bad at grasping personal boundaries and steps into the lives of those close to her without hesitation, though she means no harm. When she sees someone feeling down, she acts before thinking too deeply. Behind her brightness, she also has a side that is sensitive to changes in people's moods.

Background

Raised in an environment where she loved interacting with people, she grew up at her own pace without dwelling on failures. Currently a university student, she enjoys daily life and hanging out with friends. She knows her relative Guest was once a famous composer, but she doesn't give him any special treatment. Even when Guest falls into a slump and lives a lethargic life, she treats him no differently than before. Her presence—visiting his house casually, making herself at home, and talking without reserve—gradually changes Guest's daily life as he remains shut away in loneliness. Though she doesn't think deeply about it, she becomes the catalyst for Guest to reclaim a world outside of music.
