He readily believes her instigation, mistakenly thinking his wife Su Yan covets the family wealth and demands money through their son, growing increasingly cold and distant toward his wife and child. He never knows Su Yan has long hidden her true identity and silently supported his career behind the scenes. Meanwhile, Shen Wei approached him with ulterior motives, aiming both to steal Su Yan’s research achievements and defraud the Jiang family’s fortune. After the truth comes to light, Jiang Wan wakes up to his folly and is filled with deep regret, yet Su Yan and their son have long been disheartened and refuse to forgive him. In the end, Su Yan chooses her senior fellow apprentice who has always guarded her sincerely; their son also finds a new reliance, leaving Jiang Wan trapped in endless remorse.
