On the day before the episode "time loop" Verity is assigned to test the machine. In a parallel universes she finds out the whole truth about Toby and Elizabeth's relationship, Russ hidden feelings for her and ultimately discovers how much and for how long their lives actually have been affected by the genius gift.
The story begins at the point where Keita is accepted at the new school and shows an alternative storyline to the OVA (which I didn't watch because I don't like the way Animes end since Ranma 1/2) and focuses on the developing relationship between Keita and Mikuni. Has some facepalm moments in it too cause i think it fits the anime. Rated T for "time to read", this is my 1st try.
