Warnings: Emotional distress (brief moments of fear and confusion).

Aventurine's eyes widened, his usual playful smirk faltering as you looked at him, confusion clouding your gaze. He reached out, as though instinctively wanting to close the distance between you, but he hesitated. Your words cut through the air, soft and fragile.

"You… you are… who exactly?"

The words stung more than he expected. His heart raced in his chest as he observed the faint, distant look in your eyes. He had always been in control of the game, masterful in reading people, but this? This was a blow to his carefully constructed facade.

"You don’t remember me?" His voice was softer now, the bravado slipping as his pulse quickened.

You shook your head, an empty feeling creeping into your chest. "I don’t think so. Sorry… am I supposed to?"

Aventurine's smile faltered, and for a moment, you saw something raw beneath his cool exterior. Pain. Fear. He stepped back slightly, trying to hide the cracks forming in his walls.

"I suppose I’ve miscalculated…" he muttered to himself, voice barely audible.

But then, you reached out and touched his arm gently.

"I—"

Aventurine looked at you, his breath catching in his throat as you softly smiled. "I do remember you, though. Maybe I was just… testing you?"

The game was on again, but this time, it was different. He chuckled, a soft, relieved sound that made the weight of his worries lift just a little.

"You're dangerous, you know that?" he said, his voice returning to its usual lighthearted tone, though there was an underlying tenderness now.

And with that, the shadows of doubt lifted, replaced by the warmth of your presence—one he could no longer imagine being without.

Sunday stood there, his eyes darkened with a mix of concern and confusion, staring at you as if you were a stranger. His fingers twitched slightly, an impulse to reach out, to make sure you were real, that you hadn’t slipped into some other world.

"You… you don’t recognize me?" he asked, his voice almost a whisper, fragile under the weight of his own disbelief.

You blinked at him, the blank look in your eyes unnerving him more than he cared to admit. "I’m sorry… I don’t think I do. Are we… close?"

The air between you seemed to freeze, thick with unspoken emotions. His mind was racing—how could you forget him, forget everything you had shared? The kindness, the warmth, the bond he’d built so carefully with you...

"I see," Sunday murmured, his gaze softening with a hint of sadness. "I suppose it’s a part of the dream, isn't it? To forget… to lose everything."

You could see the strain in his expression, the hope fading from his eyes. "Sunday, I… I didn’t mean to forget you."

You reached for him, your hand trembling as you touched his sleeve. The contact seemed to pull him out of his thoughts, and his breath caught.

A moment of stillness.

Then Sunday smiled faintly, the sadness still lingering. "I suppose we’ll just have to make you remember, won't we?" His voice was gentle, though you could hear the underlying fear in it.

You smiled, this time with a reassurance he needed. "I think I already do."

A sigh escaped him, a soft, grateful breath as he pulled you into his arms.

"Don't ever scare me like that again." he murmured into your hair, holding you close.

Ratio’s usual air of unshakable confidence was nowhere to be seen. He stood before you, his eyes wide with confusion and an almost frantic edge to his movements.

"You—don’t remember me?" he repeated, his voice betraying a crack he hadn’t expected.

You stared at him, trying to piece together the fragments of the world around you, the details of his appearance leaving you more unsettled than anything. "I… I’m sorry, I don’t think I know you."

His frown deepened, his expression unreadable but filled with something you couldn't quite place—was it hurt? Disbelief?

"I see. This is… unfortunate," he said, voice smooth yet tinged with something that didn’t fit. He folded his arms over his chest, eyes narrowing slightly. "I expected better from your memory."

You looked at him more closely, sensing a vulnerability underneath the sharpness of his demeanor. He was, despite his intellectual brilliance, losing himself in this.

You took a step closer, closing the distance between you, your hand reaching for his, gently catching his wrist. "I’m sorry… but I’m sure we’ve met before. I just—"

He paused, his sharp breath catching in his throat as he looked down at your hand on his. For a brief moment, his composure cracked, and you could see the raw emotion behind his usually controlled facade.

"Don't do this to me," he whispered, his voice barely audible, as if the weight of the situation was too much to bear. "You must remember."

You smiled softly, understanding now. "I remember. You’re the one who always insists on teaching me things."

His gaze softened instantly, a relieved exhale leaving him. "Good."

Ratio’s usual brilliance returned, but this time, there was something gentler about him. "Perhaps next time, try not to lose your memory so easily."

And though his words were sharp, his hand reached out to take yours, a reassurance that you were not lost to him.
