Miharu is the only tenant in a boarding house, but even after everyone left, he decided to stay
Now he lives with Heita and his grandfather because he didn't want to leave Heita's side
As Heita grows up more, Mahiru wants him more, but doesn't know how to handle his feelings
A lone tenant remains in a now defunct rental complex, living with the owner and his grandson. Why is he so persistent and refuses to leave? Is it his inability to live by himself? Or is it something else altogether?
