There will be no wedding, sir!

Married? For the light one? Me, a hereditary dark witch? Yes, you are entertainers... The groom will run away, his heels sparkling, a minute after the engagement! Moreover, he is a quiet son of Lord Lightwood. His father is someone to be feared and avoided. A powerful and dangerous light magician, rector of the capital's academy, whose name still haunts me in nightmares. After the wedding we will become relatives?! Well, I do not. Getting rid of his son’s hand and heart is now a matter of principle. Stop. What do you mean - the groom is not a son?! Lord Lightwood, are you kidding? There will be no wedding!
