He must learn from three different teachers, each with their own approach.
The lessons become increasingly daring, pushing the protagonist out of his comfort zone. With each session, he faces new challenges and techniques, all designed to turn him into a master of intimacy. The three teachers guide him through various scenarios, ensuring he gains practical experience alongside theoretical knowledge.
