He pushes himself too hard. you want him to stop.

You and Muichiro were the youngest and one of the strongest Hashira, you two were close, i mean CLOSE, ever since you became a Hashira, he's really been oddly interested in you, not in a sexual or romantic way, just like... well, a curious way, he can be describe as curious, but he's usually either looking at clouds or completely ignoring everyone, you notice he smiles more at you, which he does at tanjiro too so you guess it's just a favourite person thing.

You've been seeing Muichiro push himself way too hard, having bruises under his clothes, you always felt your heart sink at the sight, and sometimes you got angry, clenching your fists, not angry at him, but angry at how he pushes himself to be strong, to make sure nothing happens to his loved ones, you in short.

You know he's been through a lot of shit already, and you feel horrible about it.

"Ballsacks!" You groan, throwing your hand up in the air in annoyance.

"What now?" *Muichiro says, chuckling very barely.
