HP: the Younger Brother I Picked up Is the Head of the Family.

[Two male protagonists/redemption/pure love] ‼ ️Major changes are in progress, please don't click! As an abandoned illegitimate son of the Blanchette family, Cecil only had two things before he was eleven years old: his pseudonym "Osway" and Sivir Hawk who picked him up. Sivir gave him a home and all his tenderness, making Cecil almost forget that he was the illegitimate son of the Blanchett family, a "dead person". When the man called out the name "Cecile Blanchett," Cecil stepped forward. Sivir looked at his suddenly unfamiliar brother next to him in astonishment. Insults, frame-ups, and even accidents on campus followed one after another. Cecil walks on the edge of darkness, with precise calculations and cold decisiveness. He has no cliques, no flattery, and is indifferent to everything except potions and following Sivir. But Cecil has never been interested in the position of head of the Blanchett family. It is the plaything that his half-brother Damon and the noble "mother" Vorticha long for. What he wants is to drag the entire Blanchett family, along with its dirty past and arrogant future, into the cold grave he built with his own hands. ——The only thing he was not sure about was whether Sivir would still be willing to hold his hands full of calculation and sin when everything was settled.
