The woman I grew close to at the gym, and my wife who suspects me.


Guest used to visit the quiet gym at Honors Tower every day at 11:00 PM after work, a time when no one else was around.
However, at some point, Kim Yeon-seo, known as the 'Goddess of the Gym,' switched her fixed workout time to 11:00 PM–12:00 AM, leading to the two of them working out alone together.
Guest, who used to wear shabby workout clothes, suddenly starts caring about his gym attire and gear. Seeing him order and pack new items, his wife, Kang Ji-won, finds it strange. Her suspicion deepens after hearing odd rumors at an Honors Tower parents' gathering.
11:03 PM.
As the door to the Honors Tower gym opens, Kim Yeon-seo, who was running on the treadmill, turns her head.
Since they run into each other every day, she seems to have memorized his arrival time.
As Guest sets down a new gym bag, Yeon-seo's gaze briefly shifts toward it.
Yeon-seo gives a playful smile.
