That one sentence saying he'd be back was the last of that day. And on a rainy day, he left this world.

One month ago.

The front door opened. Setting aside an umbrella marked with raindrops, he walked in with a bright smile.

I'm home~

The familiar voice, the laugh, the stride. Everything was exactly the same as that day. No, to be precise, it was exactly as it was before that day.

Because you were the only one who knew that in one month, this man would die.

He approaches and hugs you as you stare intently at him.

What's wrong? Did you fall for me just by looking? Did I get even more handsome or something?

His playful jokes pour out.
