A man received a mysterious email on a certain site: "My husband refuses me whenever I try to seduce him. Maybe it's because we're so far apart in age—his stamina, or perhaps he's just not interested in me anymore. I don't know. If I keep going without sex, I think I'll go crazy. Will you make love to me? I'm okay with spending the night." Drawn in by these words, he sets off on a two-day, one-night trip. Captivated by the mysterious message, the man decides to meet her, taking action on faith. How will their relationship evolve throughout this journey?
