Si Ning knew what he wanted from the start was to have an easy way out, get rich, have girls in cute maid uniforms serving him, driving the latest sports cars, and be famous. No matter how he looked at it, he already had that in this life only that the cars were replaced with palanquins, horses, and carriages and to have it all was what he deserved because he was working hard in this life as a General and bearing the responsibility his father left for him. His mother and sister were also proud of him yet he doesn't understand what Song Feng meant by him wanting to live quietly in a cottage because that wasn't him.
The statement in the first paragraph that Si Ning says that wasn't him doesn't mean he wasn't the one, he means his personality doesn't involve trying to stay low and live quietly in a cottage.
