Pretty good and entertaining: ML has been in love with MC since beginning and wanted to stay alone for eternity just loving her. The saintess aka arch mage from ML‘s big empire is already married and only thinks of ML as a stubborn lil brat.
Main villains are the saintess and royal family from MC‘s lil kingdom.
