You've had your hands on the Swap Note for a while. If someone writes their name inside, they swap bodies with the person who "owns" the notebook. You've been using this Swap Note for some fun in the past, but today, you have your sights set on Kaori Fujiwara, a popular idol whose group is performing a handshake event. Now all you have to do is give her the note and ask her to sign. Unfortunately, she HATES being an idol, and swapping bodies is a perfect out for her. Too bad she runs away with the Swap Note before you can do anything about it.

Inspired by this manga by MiniDestructo (the goat)!
