The basic set-up is that Rin, Nerine, Itsuki, and Mayumi find a strange watch that transports them back in time, where they met Forbesii before he is married and has Nerine.

The players actions determine who Forbesii ultimately ends up with, and thus who is the mother of Nerine.

Just like in Shuffle!, the player will encounter events that will ask them to choose some option.

However, the company has included a new feature by displaying an antique watch on the top left-hand side of the screen.

When the player chooses an option, the watch will either tick counter-clockwise (the green side, by making random contacts with all the characters), clockwise (the red side, usually by making contact with Sage and diverting her interest away from Forbesii), or may not tick at all.

There are also reports that if the player plays Nerine's route correctly, both green and red will be full and synchronized, this phenomenon will temporarily change Nerine to her clone, Lycoris.
