- Description from Novelupdates

Unable to control his mouth, Lin Jian Yin scared away eight previous girlfriends and six previous managers thanks to his poisonous words. Finally unable to stand it, he goes to a strange antique shop recommended by his friend. The shop supposedly has something that can help him.

Even though a Nintendo that plays cartridges is a bit outdated, and probably no one plays it anymore, isn’t it too exaggerated to place it in an antique shop to sell?

After returning home with a Nintendo, Lin Jian Yin inserts the cartridge that the owner sold to him at a huge discount. Only then does he discover that this is actually a simulation game. The female protagonist isn’t a cute loli, nor is she a mature woman. Rather, with her old lady hair and blue-white slippers, she is such a frightening woman that calling her a Taiwanese babe would seriously be insulting Taiwanese babes.

Gods! His mission is actually to help this woman marry a perfect prince! How is that possible!!!

Wait, as the main guy protagonist, Lin Jian Yin actually isn’t the prince. Then, then, who exactly is he… No, “what” exactly is he?
