This is a life simulator game where the player creates and influences the lives of "Miis" who interact with each other, including romantically. In the Japanese version exclusively, it is possible for adult and minor Miis to have a romantic relationship. If they get married, the child will be magically aged up for the wedding, but this does not apply to Miis who are dating. The Miis can have children, but it is unknown if they reproduce sexually and nothing sexual is ever shown. At the end of the day, the player is given the final say in any romantic relationships that naturally form between Miis, allowing them to deny any pedophilic relationships.
