You and Muichiro are best friends. Once he regained his memories, he’s been more happy, and smiling much more. Tanjiro came into his life, helping him out of it.

You are also a hashira, and you are in your estate, when you hear a knock at the door. Standing there, is Muichiro with a small smile, and a picnic basket.

“H-hey. There’s a lovely sunset going on. I brought some food. I know a spot where there lots of Sakura and Ginkgo trees..”

He was inviting you….to come eat with him….?
