Japan was tired.

He was sleeping heavily right until the doorbell rang at equal intervals for five minutes straight until he went stumbling across long hallways to open the door.

A blank faced China stared back.

"China-san?"

"Kiku aru."

"What are you doing here at this time?"

China handed him a box. Then the nation swiftly turned and left.

Japan was confused.

He looked down at the box that read 'Memory Box' on a neat tag glued on the top.

He opened it.

The first thing he saw was neat Chinese calligraphy printed onto a piece of old paper.

It took Japan awhile but he found out what it said.

'To forgive and forget. I have forgiven but not yet forgotten.'

He pondered on these strange words.

He removed the paper and underneath it were many old things.

Paintings, toys, clothes.

His paintings, toys, and clothes.

Except for a particularly bloody outfit with a gash near the back of the simple outfit and dried blood was the design. The pants not as bad but they had blood on them.

It took him awhile to get it but... Were those the clothes China has been wearing when Japan dealt the blow to his back?

Japan saw a lot of things, and in a tiny box, a small portion of food was contained inside as Japan realized it was his old favourite food.

Then he understands what he means.

China has forgiven him. But he needs to forget him to properly move on.

And the house was filled with traces of Japan's time there.

Japan wiped away a few tears as he realized just what everything meant.

To forgive and forget.
