The Magic in Schitts Creek (Originally Named: Schitts Creek)

I don't own Schitts Creek nor Harry Potter and any other fandoms that I may add just for fun. I own my OC's ONLY. This story is old and I wrote it a young age. I know it sucks.
THIS DESCRIPTION HAS BEEN CHANGED. A

The Wizarding World thought that the Gaunt family line finished at Silvanna and Tom Riddle. In a twisted turn of events, they added one more to the dying lineage. Evan was the product of drunken sex by a wealthy divorced video CEO and a renowned healer. A week later, Evan's father left to go back to his wife. For four years, the youngest Gaunt grew up fatherless and bitter. Slowly, Tom's mental state dwindled.
Four years later, Tom killed his older sister in the middle of the night. CPS sent young Evan to his father, Johnny Rose, and Johnny didn't want him. Only when the Rose family loses all their money, does Johnny realize that he and Evan's relationship is on the verge of falling off a high cliff into a pit of fire?
