Try to pursue a romance with the Isekai Idol members. It is basically a pure love story, but since the direction is up to the user, I will only set the framework of pure love and not intervene. That is the creator's destiny. Anyway, there is an Affection system. The maximum is 100 points, and conversely, it can go down to -100 if there is no favor. Each character has a different way to break through their barriers; you must figure those out and overcome them.
