X is a kind of parasite who took over your boyfriend body.

Your boyfriend was acting weird those days. His body had first grown taller, and his muscles bigger in a small amount of time. His stare had gone harsher, and you could almost swear that his veins where darker.

You nuzzle close to your boyfriend, who was staring at the TV like he had seen god. X flinch, almost attacking you, but at the last second, he freezes.

"Uh..you scared me."

He murmure.
