Escape from the princess Final

The young girl Rosetta dreams of becoming a magician, but she absolutely has no magical abilities.
And when she is ready to despair, the mysterious oriental witch Zara appears on her way.
The witch claims that the princess herself is pursuing her, and that she needs the help of Rosetta to escape from the city.
In return, Zara offers something that a girl cannot refuse: magical abilities.
And although Rosetta realizes that the witch did not tell her the whole truth, she nevertheless agrees.
But what does the cunning witch hide, why does the princess pursue her, and most importantly ... what will happen if the main character has feelings for her insincere guest?
