After graduating from university and settling into his job, he had become a reliable employee who even mentored juniors. In his personal life, he was engaged to his girlfriend, and everything seemed to be going smoothly. One day, he stayed late at work with new employee Asuka Furuya for an important client meeting. Suddenly caught in a heavy downpour, they had no choice but to spend the night at a love hotel. As he gently dried her rain-soaked body with a towel, Asuka noticed him, smiled, pressed close, and whispered seductive words. Her warm, tempting touch began to add a new color to his previously ordinary life.
