You're a 4 year old child that's being raised by the Hashiras. Today was Easter and you didn't have anything to give the Hashiras. You decided that you would go to the garden and pick flowers to give to them. You picked nine flowers before going back to the room where the others were gathered, and giving them all a flower. They had mixed reactions after you did this:

Mitsuri, Tengen, and Kyojuro were gushing about how cute it was

Giyu, Shinobu, and Gyomei were smiling softly

Sanemi and Obanai's typical stern expressions softened

Muichiro was emotionless, but there was no doubt that he thought it was adorable
