The moon hung low in the velvet sky, casting a silvery glow over the grounds of Hogwarts. You walked beside Mattheo Riddle, your hand brushing his, though he didn't take it. You were used to it by now-being a secret, being hidden. It wasn't what you wanted, but you loved him enough to endure it.

"Do you ever think about what it'd be like if we didn't have to hide?" you asked softly, your voice carried away by the cool breeze.

Mattheo glanced at you, his dark eyes unreadable. "You know why we can't."

You bit your lip, suppressing the ache in your chest. You had been together for nearly a year and a half, and though every stolen moment with him felt like magic, the secrecy was suffocating.

"Right," you murmured, your voice barely audible.

Before Mattheo could respond, voices echoed nearby.

"Riddle?" Theo Nott's voice was unmistakable, followed by the sound of laughter.

Mattheo tensed beside you as his group of friends-Theo, Enzo, Pansy, Blaise, Daphne, Astoria, Draco, and his older brother Tom-emerged from the shadows. They stopped in their tracks, eyes flitting between you and Mattheo.

"Why are you hanging out with a Hufflepuff?" Theo asked, his tone laced with disbelief and a touch of mockery.

Your heart sank as Mattheo took a small step away from you.

"She's just my partner for a project," he said quickly, his voice casual, as if you meant nothing.

The words hit you like a curse. Just a partner.

Pansy raised an eyebrow, her lips curving into a smirk. "A project, huh?"

"Speaking of," Theo chimed in, grinning. "There's this girl in Ravenclaw who's been dying to go on a date with you, Mattheo. You interested?"

You turned to Mattheo, your heart pounding in your chest. Say no. Please, say no.

Mattheo hesitated, then shrugged. "Sure. Why not?"

The world seemed to tilt beneath your feet.

Theo clapped Mattheo on the back, and the group moved on, laughing and talking as if nothing had happened. You stood frozen, the weight of Mattheo's betrayal crushing you.

"Y/N, wait-" Mattheo began, but you couldn't bear to hear his excuses.

"Don't," you said, your voice trembling. "Just... don't."

Later That Evening

You sat on the edge of your bed, staring blankly at the wall. The pain in your chest was unbearable, a hollow ache that refused to fade. A knock at your door pulled you from your thoughts.

"Y/N?" Mattheo's voice was quiet, hesitant.

You didn't answer, but he stepped inside anyway. He was holding a neatly folded shirt and a bottle of cologne.

"I need your help," he said, avoiding your gaze. "With the date."

You blinked, disbelief washing over you. "You want me to help you get ready to go on a date with someone else?"

Mattheo flinched at the venom in your voice. "It's not like that-"

"Then what is it like?" you demanded, standing up. "Because from where I'm standing, it seems like you're perfectly fine pretending I don't exist."

He sighed, raking a hand through his hair. "You know it's complicated, Y/N. I-"

"No," you interrupted, your voice trembling. "It's not complicated. You're just a coward."

His head snapped up, his dark eyes narrowing. "What do you want me to do, Y/N? Lose my status? My friends? My family?"

"I want you to admit you love me," you said, your voice breaking. "I've spent the last year and a half hiding in the shadows for you. I've been nothing but loyal to you, Mattheo. And for what? To hear you call me a project partner and agree to go on a date with someone else?"

He opened his mouth to speak, but you held up a hand.

"Don't. If you can't say it-if you can't love me out loud-then this is over."

Silence stretched between you, thick and suffocating. Mattheo looked away, his jaw tightening.

Your heart shattered all over again.

"I thought so," you whispered, your voice barely audible.

You brushed past him, your vision blurred by tears. As you walked out of the room, you didn't look back.

And for the first time in your relationship, neither did he.
