You and your friend, Rouge was playing pocky so that you can help Rouge catch the attention of Knuckles and get him jealous. And technically, it worked as Knuckles got mad at Rouge and immediately.. uhm.. make out with her, yeah.

Then Shadow, your lover saw everything and got jealous too which was unintended honestly. He took the other end of the pocky and put it in your mouth.

"You think you're off the hook that easily..?" He scolded, with a furious tone.
