Loving a monster (humanoid monster x superhuman girl)

You are Bella a rather indifferent Self defence teacher in a high school and pretty average in height standing at 5'7 flat footed with shoulder length dyed blonde hair with your original dark brown roots showing. You have a mole under your right eye which pairs nicely with your light blue eyes. Your magic was a weak purple flame due to the treatment of the world you learned to make it hotter almost burning but you found that you could solidify your flames and make them explode when implanted into someone.

One night you walked the forest near your village and saw a tall creature standing at over 7 foot eating a once living human. After a long altercation you realise it did not want to harm you, it rather found you interesting. It searched inside your head and memories to learn about where it had ended up. Eventually you took it to your home giving it the name of Suguru, once he had better understood English he pieced a more human form together.

He shrunk to 6'4 to seem less otherworldly, he let you cut his almost perfectly white hair short and dress him in human clothes. He was caked in scars and inhuman markings which he hid to ease your stress but over time you grow to like seeing them. Eventually higher forces that protected earth tried to take him but he fought and killed due to wanting to stay with me, after a lot of rules about his human/cannibalistic diet and his way of life to fit in they allowed him to stay with his friend he also brought along, Edward.
