Samuel accidentally traveled to a parallel universe and obtained an Emotional Value system. As long as he could make other people's emotions fluctuate, he could constantly enhance his performance in his subjects by his Emotional Value. From then on, Samuel resisted the pressure and kept surpassing people who were usually far ahead of him. He ended up defeating a foreign contestant who provoked him and became famous all over the world.
Samuel Yerkes married Wendy Lake due to his family's decline and gave her his corneas. But he was thrown out of the Lake family after Wendy’s eyesight was restored, and the Lake and Zeus families even plotted to have him killed in a car accident. Luckily, Samuel formed ties with the perpetrator of the car accident, Sienna Yale (the most beautiful woman in River City), and the blood dipped into his mother's jade pendant awakened the Devil of Essence, who passed on profound magical powers to him. In return for Samuel’s curing the chronic disease of Mr. Yale (namely Sienna’s grandpa), Sienna promised to find out the truth about his parents' death three years ago. After that, Sienna expressed a liking for Samuel and got involved in his revenge against the Wells, Zeus and Lake families.
