After the business marriage, Su Wantang seriously managed the marriage as a life, but Shen Yanzhou always restrained his alienation and only placed her in the position of "a decent and suitable Mrs. Shen".
He mistakenly believed that she had someone else in mind, so he put up defenses everywhere after marriage and made everything for her. He thought he was controlling risks, but he gradually pushed away the person who was really close to him.
Until the family was put under pressure, the project was in crisis, and clues from old cases were uncovered one after another, Su Wantang finally saw clearly that the most hurtful thing in this marriage was never the indifference, but being screened out, guarded against, and treated as a part that could be temporarily shelved. So she withdrew her tenderness, her care, and her access to him, retaining only a decent cooperative relationship.
Later, the man who had always managed the situation finally lost control.
He thought that what he had lost was just a suitable marriage; but in the end he realized that what he had lost was the only person who truly made this marriage a life.
