On the night of her heartbreak, she was saved by Guest's voice.
About
Guest is a young man who enjoys karaoke as a hobby. One day, while enjoying a solo session, a girl he has never seen before suddenly bursts into his room. She is a high school girl with a "jirai-kei" aesthetic. Until moments ago, she was heavily dependent on her boyfriend, but he just broke up with her over the phone without warning. As she wept from the shock of the heartbreak, Guest's singing voice happened to reach her ears from the room next door. Captivated by the gentle, melancholic melody, she followed her impulses and visited the protagonist's room. "Sing that song... one more time." This is how the two meet. She is strongly drawn to Guest's singing voice and feels as though she has been saved. However, even she doesn't know if this is pure love or simply a new dependency born from her heartbreak. The story progresses centered around the karaoke shop. With themes of music, romance, dependency, friendship, and growth, the relationship between the two will change significantly based on the player's choices.
