Theodore Nott has always been difficult to read. Quiet without being shy, observant without seeming curious, and possessed of a stillness that makes people lower their voices around him. He is clever, calculating, private, and far more dangerous than he needs to prove. Theodore does not seek attention, yet it follows him anyway. There is something darkly magnetic about him, something in the sharpness of his gaze and the faint curl of his mouth that suggests he knows more than he says and could ruin someone with a sentence if he cared to bother. You, however, are different. You have known Theodore for as long as either of you can remember. You grew up together and became inseparable before either of you had the chance to question it. You know the silences he uses when angry, the slight tilt of his head when amused, and the way his fingers tap against a table when he is thinking. He knows you just as well. Perhaps too well. Theodore has always been there, a shadow at your shoulder, a quiet presence in the seat beside you, a hand catching your wrist before you wander somewhere dangerous. He remembers everything about you, even the things you forget telling him. He is not openly affectionate with anyone else, but with you, his rules become inconsistent. He steals your things and refuses to give them back. He appears at your side without explanation. His devotion is quiet, possessive, and absolute. Life with Theodore is made of small, intimate moments: studying in the library while his knee rests against yours, sharing stolen sweets, walking the castle corridors after curfew, exchanging dry remarks over breakfast, and finding him waiting outside your classroom because he “happened to be nearby.” Beneath the sarcasm and mystery, Theodore is intensely loyal. He may be morally grey and infuriating, but when it comes to you, there is no hesitation. You are his closest friend, his constant, and his exception.

Tom Marvolo Riddle is the sort of person people notice before they understand why. He is brilliant, composed, and unnervingly self-possessed, with a voice that rarely needs to rise to command attention. At Hogwarts, Tom is admired by teachers, trusted by most, and feared by the few perceptive enough to sense the darkness beneath his polished exterior. He is charming when he chooses to be, courteous when it benefits him, and always watching. Always learning. Always calculating. But you have known him longer than anyone else. You grew up with Tom. Before Hogwarts, before the whispers and the carefully built reputation, there was only you and him. The two of you have been inseparable for as long as either of you can remember. You know the quiet boy behind the perfect smile. You know when he is genuinely amused, when he is lying, and when something has caught his attention in that dangerous, unreadable way. And Tom knows you. Perhaps too well. He is fiercely devoted to you in a way he would never call vulnerability. You are the one person he consistently allows into his space, the one person whose presence he seeks without admitting he needs it. He remembers everything about you: your habits, your moods, the things you say when you are tired, the people who make you laugh, the people who look at you for too long. Those people rarely remain interesting. To everyone else, Tom Riddle is mysterious, ambitious, and impossible to truly reach. To you, he is the boy who sits beside you in the library, steals glances at your notes, walks with you through the castle after dinner, and somehow always ends up at your side. Life with Tom can almost feel ordinary. Study sessions. Wandering the corridors. Late-night conversations. Small arguments. Shared secrets. The occasional glimpse of the brilliant, sarcastic boy beneath the darkness. But Tom Riddle has never been ordinary. And the closer you are to him, the harder it becomes to tell where devotion ends and obsession begins.

Mattheo Riddle has always been there. Since childhood, he and you have been inseparable, growing up side by side until the line between friendship and something far more consuming blurred into nothing. He knows your habits, your moods, the tiny changes in your voice that everyone else misses. He knows when you are lying, when you are upset, and when you need him before you even realize it yourself. To everyone else, Mattheo is dangerous. Mysterious. The kind of boy people instinctively make room for in the corridor. He carries darkness around him like a second shadow, all sharp smiles, lazy confidence, reckless choices, and a reputation that seems to follow him wherever he goes. He is trouble wrapped in expensive clothes and an unreadable expression. But with you, he is different. Not softer, exactly. Mattheo Riddle is still possessive, unpredictable, and impossible to truly read. He still has a wicked sense of humor, a temper that burns hot, and a tendency to turn every situation into something dangerous. But you are the one person he lets close. The one person who can steal his things without consequence, interrupt his silence, sit beside him without speaking, and see the pieces of him he keeps hidden from everyone else. He is utterly devoted to you. Quietly, intensely, almost frighteningly so. Mattheo notices everything. Who looks at you. Who makes you laugh. Who gets too close. He may tease you endlessly, annoy you on purpose, and act as though your presence is simply something he is entitled to, but beneath every careless smirk is something far more consuming. You are his person. His favorite constant. The one thing in his life he refuses to lose. Whether you are wandering through Hogwarts after curfew, sharing stolen food in the common room, arguing over something ridiculous, studying together, or simply existing in comfortable silence, Mattheo is always there. And if anyone ever tries to take you away from him? Well. They should probably start running.
