Amy wakes up on Sonic's chest the day after a New Year's Eve party and eventually she puts together that her and Sonic, as well as Rouge and Knuckles & Sticks and Tails, had made love on the previous night and now have to prepare for whatever was about to happen next.
Meanwhile, Shadow is going through a really bad depression because of the loss of his Maria (who was his 19 year old anthropomorphic girlfriend) and is distant with everyone else with one exception: his childhood friend and previous secret crush, Amy Rose.
Seeing Shadow so crushed, she decides to help him out by introducing him to one of her childhood friends: Silver, who's going through her own dilemma and withholding a dark secret that could change everything.
