Why didn't Zhao go to the grave after Ruan Wan died?

Because Ruan Wan's death is directly related to him, Ruan Wan would not have died if he had not been asked to attend the concert when he got married. Besides, I don't think Zhao Shiyong is a man. As a child, he needs to rely on his parents. I wonder why Ruan Wan was asked to solve his problem after his accident, but he didn't solve it himself. Because he is not a man, he has not grown up and needs to rely on his parents, so he regards Ruan Wan as her parents to solve his problems. So I think Zhao Shiyong didn't have the face to see her, Ruan Wan lost, because he shouldn't love this man. Ruanwan will not die for this. Thank you.
