I refused to bow to fate and battled my stepmother in a contest of wits. Then one day, I suddenly discovered that there was a huge secret beneath her beautiful skirt!

A few things to know before reading:

1. The male lead won't suffer a tragic ending, but the romance only officially begins after he turns back into a man. At first, both of them want the other dead.

2. Includes Silver Tamama, with a little bit of silliness.

3. The historical setting is heavily altered and mixed, so please don't take it too seriously.

Theme: There really isn't one.
