One Man Band System

Favoritism is a common family story, but what happened to an 18-year-old named Eric was different. On his older brother's wedding day, he was falsely accused of sleeping with his older brother's fiancée, his future sister-in-law.

With video evidence, he was thrown out by his family, without even giving himself a chance to explain or defend himself. When he claimed he hadn't done it, no one in his family believed him. Even his girlfriend, who had been with him since childhood and should have known him, immediately broke up with him and turned to his older brother.

While he was being thrown out by his family and was wandering around, a lawyer called him and informed him that he had received an inheritance from a grandfather he claimed to be his grandfather, but who he clearly didn't know.

This changed everything, because in addition to receiving the sudden inheritance, he also received a system that propelled him to success and fame as a musician. What will happen to his life? Will his family return after he's become famous?
