His Royal Highness the Crown Prince's Fierce Little Wife

Have you ever experienced one hundred years of solitude? Standing apart from the crowd and watching other people's joys, sorrows and joys but unable to do anything about it? The real adventure didn't begin until I met the person who would bring me into contact. This other world is full of suffering, but it becomes so beautiful because of you. A five-year-old cute little loli, and a ten-year-old arrogant young prince, are in different dimensions, protected by a group of cute mythical beasts. They work together to level up and fight monsters. Why fight alone when you can fight in a group?
