In the eyes of outsiders, Chen Mo is just an ordinary translator working from home, but in reality, he is a top cybersecurity technology expert. His wife, Su Nian, is sent on an overseas assignment to Sweden. Chen Mo notices an emotional shift in her and quietly replaces her birth control pills with folic acid tablets as a test. Su Nian gets entangled with someone else abroad and becomes pregnant. After the truth is uncovered, Chen Mo decisively files for divorce, letting go of the three-year marriage. No longer hiding his strength, he returns to the industry to showcase his skills, building a successful career through entrepreneurship. Facing subsequent reunions with his ex-wife, he completely lets go of past entanglements, focuses on his own life, embodies a man's clarity and independence, knows how to cut losses in time, and rushes toward a brand-new life of his own.
