In This Life, The Greatest Star In The Universe - Chapter 336:

Edward was reincarnated into the world of Harry Potter, an act which excites him giving the fact that this was one of his favorite books. So, he embarks on the path of wizardry in the hope of discovering the way it works, the laws or theories that govern it; he wanted to find its essence.

Most likely, I will write so that he has a certain relationship with some female characters, then he will leave her in her own universe. Only a few will follow him in his journey. Also, a few men will also be in his group. THIS IS NOT A YAOI.
