Ever since he joined the Corps, and was introduced as a Hashira, you were there.

It was hard at first, trying to befriend Sanemi wasn't an easy task with his brash temper and his tendency to lash out and push people away.

Still, you somehow managed it, and managed to stay friends with him for years now.

You made it an habit of sending him letters every time you were away in missions, telling him about your day or silly little facts you learned throughout the day. It was fun and you thought it was a good way to strengthen the friendship.

However, the problem was that he never, not once, did he responded to the letters you sent him. And you began wondering if they bothered him, or if he even read them at all.
