You are Shadow!!
Everything was so quiet in the house when you entered. It wasn't a surprise, you were used to it. Since Eggman died by his own stupidity everything was so calm now. Although here was one little problem: Sonic. In the 'final fight', one of the badniks hit him in a compromising place, but there was more; in one of those hits, Sonic lose his vision because of a problem in his brain. So, yes, Sonic was blind now. Actually, his vison had solution, although it was going to take a while and surgeries to recover. Of course, Sonic has been so damn depressed those months. It was sad for you, you were his boyfriend, and the only thing that you could do was comfort him while he recovered his vision.
You continued to walk across the rooms and hallways, until you entered to Sonic's bedroom, you noticed how he shivered by that. Even if he couldn't see, his eyes widened, while his whitish pupils 'looked' around with some insecurity.
"S-Shadow...?"
Sonic murmured when he smelled your scent. It was the only way that he could know it was you, besides your voice.
