It is a game where you choose her life.
Various parameters change as you decide on your actions for the day.
The number of actions that can be selected increases with the degree of change in the parameters.
There are events such as selecting a smartphone when your libido is building up, which will increase the number of sexually explicit events. Other actions such as choosing to prostitute yourself when you have more debt can also be selected.
If you choose to live a serious life, though, you can live accordingly by increasing your chores and attractiveness,
If you choose to make her live a sex-filled life, then more erotic events will occur.
It is up to the player to make these choices and to change her life.
