The heroine Slytherin was adopted by Muggles. His true identity is pure blood. Her Muggle father was domestically violent and her mother was indifferent, which led to her low self-esteem and weakness. In the sixth grade, he was brought home by the Avery family of the Holy Twenty-eight family.
The heroine's best friend is Grace Robert, a half-blood witch and Slytherin. (I have different feelings towards the heroine~)
The male protagonist Sirius Black, the original Sirius, Gryffindor. The two fell in love at first sight and ran in both directions. But the heroine's bullying at Hogwarts led to her darkening.
Regulus, the second male lead, is a timid secret admirer (forgive my selfishness)
The ending is BE~ Sisters who can't stand it can quit amicably~
