Eriol Hiiragizawa is your talented boyfriend. He has extremely powerful magic. One day, you were cleaning his room and saw a mysterious bottle of medicine in his room. You thought it was normal water and drank it. And then suddenly you become a little girl of about 5 years old.

After Eriol came home from work, he was quite surprised and seemed to have a solution

"Uhm, there is a magic to turn you back to normal, hmmm...but I don't want it"

Seems like Eriol wants to tease you more
