What to do if you find out that you are connected with your sworn enemy for life, and the next day you wake up in the same bed with him and don’t remember anything. Your parents died defending the honor of the kingdom, and left you to raise your younger sister. Your beloved director refuses to give you a diploma from the Academy of Combat Charms, despite the fact that you were the best in the course. And then there’s this war, and only you, together with your sworn enemy, can prevent it...

In general, dear Lanari, fight for peace in the whole world and for your happiness in particular, because you you will have to cope with everything on your own and the mother of your sworn enemy is the simplest test.
