The game allows the player to set relationships between protagonist and/or other characters. It can come in the form of selecting among the predefined relationships or simply writing them in. In the latter event, some games are able to recognize certain inputs and act on them. Most of the time, the games introduce this mechanic to avoid the incest ban on certain distribution platforms. Frequently, the developers or the game hint which relationships are the "correct" ones.
