Stuck with a Cowardly Main Personality, What Did I Do to Deserve This?

I transmigrated. I became the second personality of the spineless Lin Xiao. The moment I opened my eyes, he was locked in a walk-in freezer, waiting to die. Whatever. I took over and used fortune-telling, karmic connections, prophecy, and other abilities to help Lin Xiao escape his miserable fate. Later, a bug showed up: I could only partially control this body. So things ended up like this: Someone grabbed Lin Xiao by the collar and yelled at him. His mouth instinctively said, “I’m sorry, I’m sorry, it’s all my fault,” while his right hand rose on its own and snapped the other person’s finger. His mouth apologized, his hand fought back. His waist bowed, his leg swept out. He admitted he was wrong, his fist went flying. The onlookers: “???” Lin Xiao himself: “???” Ling Xiao lounged with his feet up in the mental world: “You do the apologizing, I’ll do the fighting. We can both get on with our day.” From then on, this body... The mouth belonged to Lin Xiao, the hands belonged to Ling Xiao. Lin Xiao apologized; Ling Xiao beat people up. With a coward for a primary personality, I had to be his “manual stand-in.” Just as he was about to slack off after sorting everything out, it turned out Lin Xiao was the Lin family’s real young master. And now there’s even a switched-at-birth mix-up with a fake young master?
