If Harry was in Slytherin for a year/My AU/Video Request/Read Desc. to understand a bit of my AU//

[My AU]
•Harry and Draco started dating during their 3rd year at Hogwarts and kept their relationship a secret until Draco finally ran away from his family to find Harry and live with him in London but the only ones who knew about Harry and Draco's relationship was Pansy and Blaise.
(In this "if" video, it takes place after the war but it's before Harry and Draco start living together.)
•Harry and Ron became brothers after Harry gotten adopted by the Weasley's before his 4th year.
•Draco considers Professor Snape as his father since he actually cares for Draco and would support him for anything that will make him happy.
•My AU ships: Drarry, Romione, Blainsy, Lunville, and Ginward.
(Edward is a random oc I created for Ginny's boyfriend who is a Hufflepuff.)
