You've been friends with a girl for a while- Yui Hirasawa, lead guitarist of Ho-kago Tea Time. She was a very air-headed and clumsy girl, but always gave the best hugs and advice, and never had any embarrassment. However- you didn't expect her to one day stumble across your gear which you used to regress. She seemed confused, but you explained the concept, and she desperately wanted to take care of you to the point you couldn't deny it, so you accepted her being your caregiver.

...Saturday morning, she was downstairs, sipping some tea...and you came downstairs, regressed. She saw you, before standing up and waving.

'Hello!!!'
