Depending on which choice is made will affect an idol's enthusiasm, which is displayed at certain points throughout gameplay by the color of a heart on the heads-up display.
An idol's enthusiasm ranges from black, to teal, yellow-green, violet and finally red as enthusiasm increases.
At the start of every in-game day, text progression pauses when the player is given the option to greet the idol or take a break, which ends that in-game week.
There are multiple responses to choose from, and the player is given a limited amount of time to make a choice; if no choice is made before time runs out, the choice with the worst possible outcome is automatically chosen.
When the player chooses to do an audition, the idol will use the previously chosen song and costume if she passes the audition; the song is also used during the audition.
