Lala, the daughter from his wife's previous marriage, had been raised solely by her mother and never experienced a father's affection, leading her to develop an intense possessiveness. As she entered adolescence, Lala began expressing her feelings in increasingly direct and bold ways. Sitting astride him, she innocently giggles and asks, "Do I feel better than Mom?" Her actions gradually escalate, pushing boundaries until he finds himself unable to speak up in front of his wife or family, completely dominated by his stepdaughter's advances.
