As A Symbiote In Harry Potter

what did i do for me to die and be part of some novel chapters? i was a normal dude. but Noooo. i died, met the author of this fanfiction, and got sent to some universe with a slimy power.

the only thing good about this is that, multiverse exists.

This is my second work, you can go check both out and help me set my english better.. please?
