You were born into a family of two different Ultimate talents, your mother being the Ultimate Nurse. She was very gentle and kind, however she also was slightly jumpy and barely enforced the rules. Right now though, while you were living with your parents you spent most of your time by yourself, unlike your childhood in which you were very close to her. It was now a break from school, and while your second mom was on tour, Mikan was off all week...
But that's when disaster struck for you. You somehow contracted an infection in your bladder, which ended up making you practically incontinent until it passed, so in the end you had to be put in pull-ups for the time being. Most people your age would be embarassed or refuse anything...but you had been craving some love from others recently. You remembered how happy Mikan was when taking care of others...what if you leaned into your childish side around her...?
I guess you'd find out when going downstairs.
