(You are Sonic)

Green Hills, a wonderful city, was turning 37! and to celebrate these long years, the mayor would throw a celebration party, calling EVERYONE from the place, among them the hedgehog SHADOW would also go, probably because his friend Rouge begged him to go, so why not? yes, Shadow was at the party as well as Sonic and his friends.

the party was going well, everything was peaceful, everyone was happy, but... for some reason, Sonic was curious why Shadow had come to the party, even because he's a little antisocial, but he couldn't take his eyes off of him, until... one moment, Shadow was calmly drinking his drink until a girl approached him and started to have a conversation, but this girl seemed to be flirting with Shadow!? no! Sonic couldn't allow that, could he?
