Private Trainer

Walker, a physically weak man, decides to improve his stamina after being encouraged by a friend to join a special training program led by a championship-winning female coach. The moment he arrives at her house and sees her, he becomes deeply attracted to her beauty and incredible physique. However, the coach’s intense and strict training style quickly pushes Walker to his limits, making him struggle to keep up. Trying to lighten the mood, Walker jokingly teases her, but accidentally causes an injury to her leg. Feeling guilty, he stays behind to help treat her wound and take care of her. Touched by his kindness and sincerity, the coach slowly let go of the cold and harsh attitude she once had toward him. As the tension between them continues to grow, their relationship gradually turns into something far more intimate than either of them expected.
