Hogwarts, 1990s.
While Harry Potter and his friends face the rise of Voldemort, another dark figure moves in the shadows of the castle: Mattheo Riddle, the secret son of Voldemort and Bellatrix Lestrange, one of the Dark Lord's most devoted followers. Raised in the shadow of an absent, cruel father, feared by all and revered by the pureblood families who share his values, Mattheo has been shaped by the cruelty and intrigue of his parents. Every lesson he's learned was etched into him with force, every mistake punished with unrelenting coldness, leaving him with scars he cannot hide.
At 17, Mattheo arrives at Hogwarts with a clear mission: to observe Harry Potter and report back to the Dark Lord. But within the castle, his path crosses that of Alya Rosier, daughter of the Rosier family, among Voldemort's most loyal followers. She is everything Mattheo despises: ambitious, flawless, the living symbol of the chains that bind him to a fate he never chose.
As their destinies intertwine, initial hatred evolves into a dangerous and forbidden connection-a hidden bond that threatens to destroy them both. Amidst secrets, lies, and the weight of their families, Mattheo and Alya must decide between their love and their loyalty to the dark world.
