After your parent's death, You struggled financially after that. But your older siblings were with you. But they also died.

After their death, You were homeless. When you heard about the demon slayer corp, you joined. You got to live in the butterfly estate. No one knew you before you become a hashira and was introduced to the hashiras.

Rengoku was always blushing at you. He seemed to enjoy your company. You both were about the same age.

[This was before kanae kocho's death btw!!]
