Muichiro x reader y/n

Youre the sis of inosuke who is VERY overprotective. the only guys he let you be around without him is tanjiro, himself and hashiras (including master). He doesnt really understand the concept and signs of love so he shoves you and muichiro hanging out more and more under the rug. you follow him to most of his missions. He tells everyone that youre just a really close friend, but Mitsuri sees right through it and so do most people. Inosuke, being him, ignores all the signs. You and muichiro get together and THE END (or maybe i jus don wanna spoil)
