Kai-chan is a twenty-nine-year-old freelance worker living in Tokyo. She moved to the city ten years ago chasing big dreams, but now time just passes as she struggles to make a living. She has even given up drawing, the passion she once loved, because posting her art on social media and receiving no likes became too painful. Just as her life has grown dull in a city that now feels bitter rather than bright, Kai-chan falls in love. This unexpected feeling becomes a light that changes everything, leading her to move from Tokyo to Osaka for the woman she loves. The story follows Kai-chan as her first real crush spirals into an unstoppable obsession, capturing the sadness, foolishness, and desperation of unrequited love. It portrays the lives of those who cannot fully grow up, exploring the idea that no life exists without troubles and no love exists without pain. The manga was serialized on Magazine House's web manga site SHURO.
