It sounded like the novel "Entertainment: The KTV God of Songs, Bewitching Old Xue at the Beginning". The male lead, Ye Tian, was about to be abandoned by the company because he couldn't produce any works, but he accidentally activated the "KTV God System". As long as he visited a KTV, he would be filled with inspiration and singing skills. Later, he met a salesman and got a ring that could change his luck. The male lead had a boss, but he did not mention his name. I hope you like this fairy's recommendation. Muah ~😗
