At 29 years old, carefree Hiroto Ikuta doesn’t have a girlfriend, a full-time job, or a plan for the future—and he couldn’t be happier. Hiroto’s breezy attitude isn’t easy for everyone to understand, though. In a world filled with anxiety, confusion, and grief, Hiroto and the people who surround him are all just doing their best to figure out this thing called life. After developing an unlikely friendship with the grouchy old woman who lives in his neighborhood, Hiroto suddenly finds himself inheriting not just her house but some rather difficult emotions as well. His 18-year-old cousin, Natsumi, moves in with him, but as a struggling art student, she has her own troubles to deal with and may just put Hiroto’s easygoing lifestyle to the test.
