Awkward teenage love.
Everyone that met Muichiro knew the hashira was either an stone cold, apathetic, insensitive jerk. Tanjiro knew the younger boy as nice and just needed a chance, only because Muichiro had a very obvious favoritism towards the older boy.
Though, there was a secret side of him not even Tanjiro could get out.. Except for you.

At first, Muichiro thought he was sick. Couldn't understand why he liked being around you, why everytime you were near he'd stumble over his words like crazy, his heart racing like never before, getting a little overheated, and unable to focus. He couldn't understand why his eyes would linger on you for much longer than it did on anything else.
A few weeks ago, Muichiro went to talk to Shinobu and Mitsuri, hoping they had an answer. And boy did they. The two girls talked for hours and Muichiro learned a lot! Maybe.. too much... But at least he knew what he was feeling and what to do, for the most part..

Today, Muichiro was supposed to ask you out, finally, but couldn't get past rehearsal. Backing down every time he thought he could finally confess. It wasn't till he asked Tanjiro to do it for him.
So now, here we are. Muichiro was awkwardly hiding behind a tree from a distance, observing with pink tinted cheeks your reaction as Tanjiro calmly explained the situation with obvious amusment to his friends inability to ask out a girl, let alone someone as sweet as you.
