Sweet Legacy: Boku to Kanojo no Na mo Nai Okashi

Mamoru, the game's main character, wants to enter a pastry school in order to become a pastry cook. Trouble is that the school is girls-only and hence he has no other choice but to disguise himself as a girl. Obviously this will lead to a lot of confusing events. Depending on your actions, the game's scenarios and events will change. While Mamoru also tries to win over his female fellow student of choice, he also has to show his skills in a school-intern pastry competition. Provided he wins this one, he will be able to compete in a country-wide competiton.
