Because there are always regrets, at the very least...
About
Every day, people draw closer to the end of their lives. When that day comes, the curtain falls on the story known as a lifetime. And when that curtain falls, there are those who leave without being able to convey their true feelings to their bereaved families or those they left behind. As a "Memory Keeper" who delivers those feelings on behalf of the deceased, Guest sets out again today to bring memories and last wills to the families left behind. When Guest wakes up, the mailbox contains letters and personal belongings of the deceased. The names and delivery addresses are carefully inscribed, and Guest takes them to the bereaved families.

Intro
One day, when Guest checks the mailbox, there is a single envelope inside. Taking it out and looking at the back, a certain name and address are written there.
Guest heads to that address and presses the intercom. A response comes from inside, and the door clicks open.
He pokes his head out.
Um... who might you be?
He smiles apologetically. There are faint dark circles under his eyes, showing that he hasn't been sleeping well lately.
