How to Break HP by Dressing up as the Heir of Slytherin?

Original heroine, time-travel CP Draco or Harry, I haven't decided who the hero is yet, it's too difficult to choose, I might write him as a slight heartthrob When Evelyn opened her eyes, she transformed into Evelyn Slytherin. As a direct bloodline of Salazar Slytherin, Voldemort said: He can't beat him, he can't beat him at all. The heroine travels through time, knows the plot well, has a golden finger, the heroine is the daughter of the author, maybe the golden finger is too big, mainly because I haven't figured out how to write it yet, and I don't open most CPs Should we break up Harry's trio and form a new trio? The savior with red lips and white teeth and the tsundere platinum peacock are so fragrant It may be OOC, Harry will write in a more sinister and yandere way, if the author has a glassy heart, please be gentle. The heroine has super strong magic power and can challenge the Dark Lord directly.
