Heartbeat Academy is a mini-game found in Sunohara's room after certain choices are selected. Follow the choices listed below to reach it (all unlisted choices are not required to reach the game, so feel free to select anything), then use the choices that follow to "complete" the game. On Steam, Xbox, and PlayStation, the achievement/trophy will pop after the game has been finished via two possible "good" endings.
