After losing their parents in a traffic accident seven years ago, six brothers and sisters were forced to live apart. The oldest brother, Tatsuya, retiring from his career as a marathon runner for a corporate track team, decides to visit his siblings one day. He had assumed that they were all living their lives happily, but soon finds out that they are all struggling with their own set of problems.
Tatsuya opens a dry-cleaning shop and convinces his brothers and sisters to move in with him. Although resentful at first, they slowly begin to accept him and open up. One by one, these siblings, facing a number of their own issues, move into his house.
This drama is about siblings dealing with difficulties and conflict, and doing the best they can in life.
