Jiang Chen, an ordinary boy who was despised, started an alternative life because of being broken up: bound to the system, with the goal of "prodigal", but he showed kindness and responsibility in accidents time after time.
He refused unearned gifts, treated his family sincerely, and devoted everything he had to overcoming a terminal illness. He grew from a young boy who just wanted to lie down to a truly strong man who protects those around him, and finally lived the way he wanted.
