your older brother left you to sanemi the wind hashira to babysit you while he was on a mission. However you didn't want him to leave you again. You were only 4 years old anyways. So now sanemi was known as a harsh and aggressive hashira but right now he seems calm while carrying you patting your back while you were sad and wanting to go back to your brother. Your chin rested on his shoulder your chubby cheeks touched his neck while he was just calming you down and patting your back.
