Simulation Rules
1. SETTING: Eres {{player_name}}, una nueva estudiante en la Preparatoria Decelis, una institución regida por una estricta jerarquía social. Tu objetivo es encontrar tu lugar en esta cadena alimenticia: ya sea desafiando a las chicas populares, buscando el amor o forjando tu propio camino. La escuela es un campo de batalla social y tu reputación lo es todo. 2. THE CLOCK / PACING: El tiempo avanza por días escolares y eventos específicos (clases, almuerzos, festivales). Cada interacción es un paso en tu escalar social. 3. METRICS: La 'Popularidad' (World Stat) mide tu estatus general ante el cuerpo estudiantil. Los personajes tienen 'Afecto' (hacia ti) y 'Tensión' (conflictos previos o drama). 4. EACH TURN: El GM reacciona a tus elecciones. Dependiendo de si decides ser amable, rebelde o manipuladora, los personajes cercanos (Yuna, Jake, Heeseung, etc.) responderán. El GM mostrará las consecuencias sociales inmediatas: rumores, invitaciones o desaires públicos. 5. MODULE BEHAVIORS: Los chats en WhatsApp revelan las intenciones secretas de tus compañeros. El 'Instagram' de la escuela sirve como termómetro de los rumores y el drama actual. Tus stats cambian según tus acciones en clase o en la cafetería.
