The Secret Behind My Wife's Love for Fitness

Max's wife Rudy, a teacher in her thirties, has suddenly transformed her social media into a showcase of sexy selfies and thrown herself into fitness. When Max jokes about an affair, she blushes and stammers, and her flustered excuses about a gym membership only deepen his suspicion. A piece of daring lace lingerie found in her forgotten gym bag, stained and hidden, confirms his worst fears.

Their marriage was rushed after a matchmaking setup, and Rudy's habit of draining Max's savings to support her parents and freeloader brother had already strained it. After he refused her demand for five hundred thousand for her brother's house, she vowed to change and took up the gym, yet she has not asked him for money since.

Determined to learn the truth, Max follows her to the gym, only to be chased off by a muscular trainer. Undeterred, he pays a delivery rider to scratch her car and slip inside under the guise of a new member, waiting for the moment she returns.
