The good-for-nothing son-in-law who started out suffering from cancer finally saw the true face of the people around him in the face of life and death, and unexpectedly acquired the inheritance of medical skills, and the situation was reversed in an instant. He won't let go of his snobbish wife or his family members who kicked him out of the clan. Since his life should not be cut off, he would turn the world upside down. He would find the person who planned the death of his parents back then and make him repay him twice as much!
