King of the Crossover

Su Yang transmigrated.

His new identity: his father was missing, his mother was dead, his looks were bizarre, his singing voice was a disaster, he had nothing to show for himself, and he was a good-for-nothing street punk living off the money his older sister earned drinking with customers!

A hellish start from the get-go!

He did get a System, but it didn't seem to have much to do with the entertainment industry...
