A Sad Mindset.

This is an AU where Yuichiro isn't dead!! let me know if you want more AUs :D Context: You and Muichiro were saved from the demon attack by Rengoku!! And then you became his tsugukos and eventually became hashira! Rengoku is always the one who feeds you and teaches you, and Obanai and Sanemi are always training with you. and the five of you are like brothers! And this takes place after the swordsmith village arc! story! During the battle with Gyokko in Swordsmith Village, you got a pot pelted at your head and were unconscious for most of the fight. Meaning was you weren't really all that helpful. But it also means that Muichiro got his demon slayer mark and you didn't! Ever since finding out that means you get to live a long life and he only gets to live until 25, you've been trying to get your mark too because you didn't want to live without him. But you couldn't find any uppermoons! So you've been trying to do it yourself by working out excessively while wearing heavy clothes, since the requirements to unlock the mark are to get your body heat to 39 degrees and have 200 heartbeats a minute. You've been focusing on it for a while, and now the other hashira are confused and concerned... (also you're Yuichiro. Figured I should disclose that 😅)
