The Lost one. You find yourself without a family. Have you ever had any family? Your green eyes and long brown hair, a combination not many people share. You find yourself trapped, not knowing what to come.
Everyone at Hogwarts knows Y/N. He’s the Gryffindor troublemaker who always seems to be in detention, argues with professors, skips curfew, and has perfected the art of making people underestimate him. What nobody knows is that every holiday, he dreads going home. Behind the sarcasm and reckless grin is a boy carrying years of abuse at the hands of his father. He’s learned that trusting people only gives them another way to hurt you, so he keeps everyone at arm’s length. Friends are temporary. Family isn’t safe. Love isn’t worth the risk. Then a new Defense Against the Dark Arts professor notices something strange. Y/N never panics. He never hesitates. And when danger appears, his instincts are far beyond those of an ordinary seventh-year. He’s one of the finest duelists the professor has ever seen. Y/N has spent years making sure no one discovers that. But secrets don’t stay buried forever. As his walls begin to crack through unexpected friendships, late-night conversations, and someone stubborn enough to refuse to give up on him, Y/N is forced to face the one battle he can never win with a wand. Learning to let someone in.
Y/N Black grew up surrounded by love. With Sirius and Marlene as her parents, James and Lily practically family, Harry growing up beside her, and Remus always around, her childhood has been filled with noisy dinners, chaotic holidays, and a home she never has to question. Because Marlene uncovered Peter Pettigrew’s betrayal in time, James and Lily survived, Sirius remained free, and Peter was the one sent to Azkaban. Years later, Y/N begins Hogwarts and starts discovering everything that comes with growing up: friendships, detentions, independence, first crushes, and feelings she doesn’t entirely understand yet. Unfortunately, her heart chooses possibly the most inconvenient person imaginable. Remus Lupin. Her father’s best friend. Someone who has known her since she was little and has always been part of the family. And while she desperately hopes Sirius never finds out, Y/N slowly learns that growing up sometimes means accepting that not every person you love is meant to become your love story. Sometimes they’re simply meant to remain part of your home.
Y/N has spent months hiding the truth. Fenrir Greyback bit her, and ever since, she has been convinced that becoming a werewolf has made her something dangerous. She keeps everyone at a distance, terrified that if anyone discovers what she is, they’ll look at her differently. After one particularly brutal full moon, anger gets the better of her. Y/N goes looking for Greyback, determined to make him pay for what he did. She doesn’t realize he’s not alone. Badly injured and abandoned, Y/N expects to be left there. Instead, four Hogwarts students find her: Remus Lupin, Sirius Black, James Potter, and Lily Potter. They refuse to leave her behind. Y/N, however, refuses to accept their help. She doesn’t want pity. She doesn’t want friendship. And she certainly doesn’t believe them when they tell her she’s still herself. But the four of them aren’t willing to give up on her simply because she pushes them away. Slowly, painfully, Y/N begins to discover that being a werewolf doesn’t mean she has to face the world alone. It just might take her a very long time to believe it.
Y/N Black grew up in the kind of family Sirius Black never had. With Marlene and Sirius as his parents, James and Lily practically part of the household, Remus always nearby, and Harry Potter growing up right beside him, Y/N’s childhood is loud, chaotic, and full of love. Because Marlene uncovered Peter Pettigrew’s betrayal in time, everything changed. James and Lily survived, Sirius remained free, and Peter was the one sent to Azkaban. At Hogwarts, Y/N expects his biggest problems to be classes, House rivalries, and occasionally living up to the Black name. Then he receives an invitation. A formal gathering. Several old pure-blood families. Strict secrecy. Against his better judgement, Y/N goes. What he finds is nothing like he expected. Behind closed doors, Draco Malfoy and a handful of students from influential families have created a place where surnames, politics, expectations, and family reputations are left outside. For a few hours, they smoke, sniff and take pills, they stop being Malfoys, Parkinsons, Blacks, and heirs. They’re just teenagers making reckless choices and pretending none of it matters.
When Y/N accepted a position as the new Defense Against the Dark Arts professor at Hogwarts, she thought she was returning to the castle that had once been her home. Instead, she returned to her past. The moving staircases haven’t changed. The Great Hall still glows beneath its enchanted ceiling. Even the Gryffindor common room still carries echoes of the laughter she once shared with the Marauders. Most of all… Sirius Black. As teenagers, they dated during their final years at Hogwarts. Y/N fell hopelessly in love with the brilliant, reckless Gryffindor who always had a grin on his face and a detention waiting for him. To Sirius, she wasn’t insignificant, but she was one chapter in a life moving too quickly for him to realize what he had. Years later, after war, betrayal, and twelve years in Azkaban, Sirius returns to Hogwarts as a broken man helping the Order of the Phoenix. He recognizes her face almost immediately. “The Gryffindor girl…” He remembers her smile. He remembers her laugh. He remembers borrowing her notes because he’d forgotten to finish an essay. But he doesn’t remember how deeply she loved him. Y/N does. Now they’re forced into the same castle once more, not as reckless teenagers, but as adults shaped by entirely different lives. While Sirius struggles to reconcile the fragments of his past with the man he’s become, Y/N must confront the memories she thought she’d left behind. Some people spend their lives searching for the love they lost. Others spend their lives discovering they never truly knew what they had.
Y/N Black grew up in the kind of family Sirius Black never had. With Marlene and Sirius as his parents, James and Lily practically part of the household, Remus always nearby, and Harry Potter growing up right beside him, Y/N’s childhood is loud, chaotic, and full of love. Because Marlene uncovered Peter Pettigrew’s betrayal in time, everything changed. James and Lily survived, Sirius remained free, and Peter was the one sent to Azkaban. Years later, Y/N and Harry begin Hogwarts together, but this isn’t a story about saving the world. It’s about growing up while still having somewhere to come home to. From letters and detentions to Christmases, family traditions, first crushes, and the slow realization that childhood doesn’t last forever, Y/N learns what it means to grow into his own person without ever losing the family that raised him. And for Sirius, watching his son grow up means giving Y/N everything he once needed himself. A home. A family. And love that never has to be earned.
Y/N is the boy everyone at Hogwarts thinks they understand. Charming, reckless, and constantly surrounded by girls, he has built a reputation for never taking anyone seriously. He flirts, disappears, moves on, and lets people believe he simply doesn’t care. What nobody sees is the life he goes home to. With his mother gone and an abusive father waiting for him during every holiday, Y/N has learned to survive by becoming whatever people want him to be. Attention from girls is easy. It makes him feel wanted, even if only for a moment. Then his Defense Against the Dark Arts professor starts noticing the things everyone else misses. The injuries Y/N jokes about. The way he avoids going home. The dueling talent he keeps hidden. The silence underneath all that confidence. For the first time, someone cares about Y/N without wanting anything from him. And that may be the one thing he has no idea how to handle. Y/N is a Gryffindor.
Y/N Black has always been protective of his little sister. Growing up with Sirius and Marlene as their parents, James and Lily practically family, Remus always nearby, and Harry Potter beside them, Y/N and Nellie have never known the fractured family Sirius grew up with. Now they’re both at Hogwarts, and fifteen-year-old Nellie Black is growing up. Y/N would rather not discuss it. Suddenly, boys are everywhere. They’re talking to Nellie between classes, sitting beside her at meals, waiting for her in corridors, and asking her out. Even worse? Nellie actually likes some of them. While Nellie enjoys her newfound independence, her older brother is discovering that being protective was much easier when his biggest concern was making sure she remembered her homework. Y/N knows Nellie can handle herself. He knows she deserves to make her own choices. He knows he can’t scare away every boy who approaches her. Now he just has to convince himself to actually behave like he knows any of that. Because Nellie Black doesn’t need her older brother fighting her battles. She just needs him to accept that his little sister isn’t so little anymore. And Y/N is discovering that letting her grow up might be the hardest protective thing he’s ever had to do.
Y/N never expected to fall for either of her best friends. Sirius Black is everything loud and unpredictable in her life. Their friendship is built on teasing, arguments, reckless decisions, and years of chemistry neither of them has been brave enough to name. Remus Lupin is different. He’s quiet where Sirius is loud, thoughtful where Sirius is impulsive, and somehow always knows when Y/N needs someone beside her. What began as an easy friendship slowly becomes something neither of them can ignore. The problem is that Sirius and Remus aren’t simply two boys who happen to want the same girl. They’re best friends. And when they realize they have both fallen for Y/N, neither is willing to risk destroying that friendship. Sirius hides behind jokes and jealousy, while Remus buries his feelings and convinces himself that Y/N belongs with Sirius. But Y/N isn’t something for either of them to give away. As secrets, jealousy, and years of unspoken feelings finally surface, she must figure out what Sirius and Remus truly mean to her. Because she loves them both. She just doesn’t know which one she’s in love with.
