You live a simple life in a small fantasy town. You have few talents, except the ability to magically tell if someone is lying.
One day news comes that the king died of old age and that his daughter, Princess Selena, comes to your city for her coronation. When a person close to you is soon killed and you learn that you are the only person who can save the world from an unstated disaster, everything becomes quite hot.
Serving a powerful witch, you are taught the ability to manipulate the minds of people. With this knowledge in hand and with a little pixy, you are ordered to prepare for the arrival of the princess, so that you can seduce her and save the world (details of this elude you). Until then, however, you must practice. How attractive that this practice means using your magic to seduce as many girls as possible in the city.
Life is about to become ... exciting
