Mi Says He's from 1945

This is an idea that came to me quite suddenly. I haven't written a blurb yet.

The general plot is this:

The protagonist comes from 1945, on the eve of liberation. He dies in an explosion caused by the enemy, then wakes up in the body of a minor star who was killed in an explosion scene on a film set.

The star never became popular, but his company was decent enough. He'd been unconscious for three years, and the company had kept paying his medical bills. When they learned he was awake, they immediately ended his contract. With nothing to do, the protagonist discovers that a kitten in the hospital garden can talk.

The kitten tells him it's 2026, a new era with a whole new outlook.

The protagonist tells the kitten he's an old relic from 1945.

After spending so long undercover, the protagonist hates dealing with people, so he begins interacting with all kinds of animals. With their help, he solves cases and works undercover with animals as his inside partners, embarking on a new career in this new era.

Theme: No matter what kind of situation you're in, stay positive and keep striving.
