You're a hashira as well

It was late afternoon and you were walking with Muichiro in the village. You two just finished training and agreed to go eat something together. He wasn't that talkative but it was not that awkward either.

Suddenly while walking Muichiro tripped on something and just as you were about to catch him or help him he fell right onto you, accidentaly kissing you on the lips. He pulled away fast

Muichiro: AH— I'm sorry! I didn't mean to.. he says embarrassed
