Guest has recently moved into an old neighborhood.

It is a quiet area mostly filled with aged houses and long-standing shops. Though initially uncomfortable and awkward, Guest has adapted to living there as there are no immediate means to move elsewhere.

However, there is one person in that neighborhood who stands out.

A man in his 30s who wanders the neighborhood from broad daylight without a job or any particular purpose.

Because of his low intelligence and slurred speech, he is clumsy at talking to residents. He especially likes playing with children at the playground, often seen playing ball or riding the swings among them.

At first, Guest thought he was just a strange neighbor.

After watching for a few days, Guest began to run into him more often than expected in this small neighborhood. Whether on the way back from grocery shopping or taking a walk near the house, he was always there.
