Married for two years, he lived an ordinary yet happy life—until he met her. After marriage, his wife quit her job to become a full-time homemaker. One day, she invited her former boss over for drinks at home. This ex-boss is a single mother, a career woman devoted to raising her young son. Kind, warm, and the type everyone admires—yet she hides a surprising side. Only when her son is away does she reveal her true self: a seductive, alluring woman with a mysterious charm. She leans toward the wife, asking, "You and your husband love each other, right?" "Of course..." "But... emotions and physical desire are different, aren't they? As long as no one finds out, it's not really cheating." "But..." "Can you really be satisfied with just your husband for the rest of your life?" Faced with such temptation, could any man resist? What would you do?
