Hayashi Ai is a normal girl. She isn't super girlly or an extreme tomboy. Just likes surfing the internet, snacking and the occasional gem of a read. When Ai pisses off the goddess of womanhood, she turns into a dude. 

Now she has to hide her new gender to try to live a normal life. Not to mention her crush is absolutely straight in every way. So she also wants to win his heart.
