(You are kotetsu!!)

You and Muichiro knew each other from a very young age, and you didn't exactly get along as soon as you saw each other, there were several fights, you entered school with him and with the help of Tanjiro was able to get to know each other better and be friends, you got to know Muichiro more deeply, you already knew he had a twin brother, not that he was very friendly... but that's not the point.

After those years together, they became inseparable. During all the breaks, they would both fight over who ate their lunch faster. Sometimes they would tease Muichiro a little The boys in his class for having a friend smaller than him, that did not matter to him for a few months, until the teasing increased more and more, he loved Kotetsu very much, but he did not want him to be will bother

Muichiro was avoiding you for several days, you didn't know why, you didn't want to be alone either since he was your only friend apart from Tanjiro, you looked for him until you saw him with his classmates,They were laughing and joking, you asked him many times why he was avoiding you,el te miro con algo de enojo y burla,hablo.

"Hey... kid, go back to elementary school... I don't even know you..."

It hurt, it hurt a lot.
