i just did this right now out of boredom i really like how this came out.

shadow is part hedgehog part demon. he ran into sonic and stared into his emerald eyes just to find that he was missing something. he asked sonic what was wrong and got a shocking response. "Shadow...I...I...I love you demon or not i still love you." shadow was shocked and after hearing sonic say that he ran off leaving sonic alone. sonic was alone and lonely, sonic knew that he was missing something and he knew that he needed shadow to feel complete but also knew that he will never feel this way since after he told shadow about his feelings and watching his love of his life run off he started to feel like he wasn't worthy of being shadow's rival/friend. he no longer desired to be with anyone. the only cure his broken heart is if shadow was with him. and that will lead to the demon's confusion.

hope you all like
