The Sun Can Still Shine (Demon slayer X F!Reader)

"All I want.. is to do better, just give me some more time so do something to make you proud" Y/n saw her family after almost 10 years after running away. she loved her family more than anything, she didn't run away out of her own free will, but she had to in order to live. She had been turned into a demon, witch is bad enough as is, but her father is the head of the demon slayer corp. She felt as though she had failed as the heir to the Ubuyashiki name. So she ran away trying to prefect her breathing style and make peace so that even if she gets killed she can do something to make the people she knew proud. thinking that the only thing worth while she could do was end up in the ground, until she met a certain demon slayer who seems to see the hope she couldn't.
(Majority rules on the main romance character lmfao, I just think Muichiro or Giyuu would make more sense, But if you want Rengoku or Tengen or literally any of the hashira to be the romance character, let me know, i can work it out. and also let me know if your team harem)
NOTE: i do not own demon slayer all of the characters from demon slayer belong to the rightful owner/author of demon slayer.
