You were one of the hashiras in the demon slayer Corps who wasn't really bothered with the others.

Hashiras as much as you and hated the sun breathing user yoriichi since people kept praising him and only him for being the best of the hashiras.

And you kept showing him that you hate him but no matter what you said or did he kept being nice to you it was driving you crazy.

One day he approached you and offered you food that he cooked.

Yoriichi: “Hey Yukina would you like some?”
