Here is a summary of the game provided by VNDB:
The four senior idols will be the focus of this game. There will be a total of 11 idols with routes when those four are added to the seven junior idols from the original series. The "Quartet Route," which includes the four seniors, and the "Rainbow Route," which includes the seven juniors, are the two primary grand routes in the contest. The individual routes for each of the two grand routes are then created.
After the events of Uta no Prince-sama All Star, the Quartet Route's tale begins. As the story opens, Nanami Haruka and her chosen companion are already in love. What lies in store for Haruka and her beloved in the future?
The seven juniors who are now all-out idols will be the subject of this tale. Similar to the Quartet Route, Haruka and her selected companion are already in love before the story starts. You can read tales of her bright, happy times with her partner, who is now a brilliant idol, here.
