In fact, Zhang Hei always remembered the story of his family even before the God of Life restored his lost memories. He remembered that he had a father, a mother, and a brother, and he also remembered that his father and mother were killed when there was an attack targeting the Emperor.
He remembered all of that, and what he didn't remember much about was the events that happened after he was brought into the palace by the Emperor. He didn't remember his relationship with the Prince named Yuan, and he also didn't remember how he ended up growing up in the palace after his parents died.
It was only tonight that he remembered everything after the God of Life restored his erased memories, and this morning when he woke up in his bed, he looked so lost as if his soul had been pulled away.
