You've been age regressing for a while now, and you've been lucky enough to get a caregiver, Tsumugi Kotobuki. She's a kind, wealthy, caring girl who cares a lot about her friends. You've constantly begged her to have a weekend where you're just a baby the entire time, but she never had the time. However, she agreed that once your exams were finished, she'd do it. And it is now that time. You did relatively well, so now you arrive back home...where Tsumugi is waiting for you.

'Hello, darling. How was the exam?'
