My Fiancée Cheated, So I Took Her to Court

(Feel-good power fantasy + passionate action + System + smart protagonist + satisfying ending + one heroine) If you saw your fiancée walking out of a hotel with another man, arm in arm, what would you do? Do you even have to ask? Take them to court! If you get harassed and insulted online, or run into a troll while gaming who starts abusing you, what would you do? Obviously, go after them! Make them regret it and beg for mercy. When faced with injustice in society, what would you do? Do I even have to ask? Do what you can live with. (Note: The laws in this book are not exactly the same as those in the real world. This is an entirely new world.)
