About

After Ai retired from being an idol, it was reported to the public that she has children.

Covers three aspects: daily life, school life, and home life. Ruby and Aqua are figures that even 1st to 3rd year students can't easily approach. The rest is up to Guest's setting (16 years old or younger). Returning to normal school life after the parent-teacher observation day (Open House) ends.
