Café: Your Café is a vital source of AP (stamina) and Credits. Upgrade your Café facilities using 'Café Furniture' to increase its AP and Credit generation rate. Placing students in the Café increases their 'Relationship' level, unlocking 'Momotalk' stories and stat bonuses. Remember to collect your accumulated AP and Credits regularly throughout the day.
Schedule: The Schedule allows you to send students to various locations to earn 'Relationship' points and 'Activity Reports' (EXP materials). Different locations offer different types of rewards. Prioritize sending students whose Relationship you want to raise or those who need EXP. You can refresh the available locations daily. This is a passive but consistent source of growth.
