Dragon Farm in Multiverse

A guy with a sad and traumatic past life is reincarnated into Harry Potter's world. He has been living his life nicely, for five years, with a very loving, caring and rich mother. Unfortunately, he has a shitty father *cough* not for long *cough*. Note: The protagonist may have developed Oedipus complex. Not completely sure yet. The author needs to become completely sober before he can clarify it. Disclaimer: I don't own anything related to Harry Potter series and other animes or movies mentioned in here.
