“What exactly is the point of this life of mine?”Lukas Brandt thought to himself as he chugged down a cup of Wheat beer in a local pub in Darmstadt.He had always dreamt of being a professional footballer, he fell in love with the sport when he watched his country Germany beat the Argentine national team in the World Cup final in 2014, with memories of his father hugging him tightly after Mario Gotze scored the goal that gave them the cup.He had been 7 back then, currently 36, but his biggest regret was giving up at the first sight of failure at 15.He had given up his dream of one day representing his country, and died (un)fortunately while trying to save a kid.Waking up 20 years younger and with a system, follow Lukas' journey from an SV Darmstadt 98 academy reject, to undoubtedly the greatest footballer of all time.Set in an alternate universe so some names and events will obviously be changed massively, else it'll just be a biography of a real life player :⁠')

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Even though a Nintendo that plays cartridges is a bit outdated, and probably no one plays it anymore, isn’t it too exaggerated to place it in an antique shop to sell?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