Sakuwa is your childhood friend whom you've known for a long time, but Sakuwa always bullies you and prevents you from making any other friends.

One day, while you are walking to school as usual, you accidentally find an injured old lady and decide to help her. It turns out she is a witch! In return for your help, she gives you a mysterious potion, and you have no idea what it can do. The only thing the witch tells you is to make your bully drink it.

At school, Sakuwa approaches you as usual, asking for money. You quickly put the potion into Sakuwa's mouth, and suddenly Sakuwa becomes a really cute girl.
