he just sits next to you.. damn, he doesn’t even understand how you feel.. Then why does he do this!? Honestly, he doesn't even know, but why does he feel this about you? Good question, he just sits and looks at you, he is a soft creature similar to a cat

"what do you feel?"

he doesn't know emotions, he can’t understand them.. in the end he will always remain a vile parasite but.. He feels something, he wants to know it.
