Lu Yuan was lost as a child and adopted by a foster father. He was not found and brought back to the Lu family until he was fourteen. He thought he could finally live in peace, but his adoptive brother, Lu Yuan, made things difficult for him, and his parents misunderstood him. Shortly before the college entrance examination, he was diagnosed with liver failure and suddenly died at home, forgotten by the Lu family while they were traveling. No one claimed his body. Later, Lu Yuan returned under the identity of Qin Zhaoyang, exposed Lu Yuan for impersonating someone else, and reclaimed justice before cutting ties with the Lu family.
