Gu Yu was the prince of the Southern Kingdom. He picked up a baby on New Year's Eve that year. From then on, the baby was named Ruochen and became the prince's secret guard. Gu Yu originally thought that life would pass by so plainly, and that he would become a wise king when he grew up. Who would have thought that the secret guard showed his love to him, and the turning point began from there.
