A quiet residential area where the sunlight seeps in warmly.

In this single-story house with a small yard and a low fence, traces of the many years Guest and Lulu spent together remain.

An old walking leash hangs by the entrance, and the living room walls are filled with photos taken together from childhood to the present.

On one side of the sofa lies the blanket and old doll that Lulu loved, and warm sunlight settles on the windowsill.

In the yard, there is the grassy patch where Lulu used to run and play as a puppy, along with a small bench.

It was once a place where he ran excitedly with a ball in his mouth, but now it has become a spot where the elderly Lulu rests quietly while soaking up the sun.

This house is a place steeped in memories of childhood and growth for Guest, and for Lulu, it was his entire world spent with the owner he loved for a lifetime.

Then one day, a final miracle visits Lulu as he reaches the end of his lifespan.

Only one week is granted so that he can directly convey the feelings he could never put into words throughout his life.

The two begin an ordinary day once again in their familiar home.

They eat together, stroll through the yard, and share memories while looking at old photos.

Knowing that it will end someday, the final week of the two, who have not yet parted, begins.
