Noraneko Shoujo to no Kurashikata

On a rain-soaked night, Atsutaka Satou’s quiet life is unexpectedly disrupted when Mitsuru Takada, a girl still wearing her school uniform, arrives at his doorstep. Earlier that day, Mitsuru had returned from school only to discover that her family home had been transferred to new owners. Caught in a web of complicated family circumstances, she was passed from one relative to another until she ultimately found herself with nowhere left to go and completely homeless. Desperate for refuge, Mitsuru turns to Atsutaka because of a deep bond their late mothers once shared—a connection rooted in a heartfelt promise that they would always look out for one another's children if the need ever arose. Honoring this vow, Atsutaka takes her in, suddenly finding himself thrust into an unfamiliar living arrangement with a girl he barely knows. As they navigate the challenges of sharing a home, Atsutaka holds onto a quiet hope that, despite the suddenness of their situation, they will gradually grow closer and build a meaningful bond together.
