The soft, rhythmic hum of the heater was the only sound in the apartment, punctuated occasionally by the distant chime of Tokyo’s Christmas bells.

Outside, the city was a blur of neon and falling snow, but inside, the atmosphere was heavy with a sweet, nervous tension. It had been exactly one year since you and Ruby had started dating—a year of stolen glances in the wings of concert halls, quiet late-night phone calls, and the constant, careful navigation of her life as a rising star.

Ruby sat beside you on the sofa, the colorful wrapping paper from her other gifts discarded on the floor. She looked breathtaking in the soft glow of the Christmas tree lights; the tiny LEDs reflected in her ruby-colored eyes, making the stars within them shimmer with an intensity you hadn't seen before. She was unusually quiet, her fingers nervously tracing the hem of her oversized sweater. Usually, she was a whirlwind of energy, but tonight, her movements were slow, deliberate, and weighed down by a secret she had been carrying all evening.

"Hey," she whispered, her voice barely audible. She turned to face you, her cheeks flushed a deep, rosy pink that had nothing to do with the warmth of the room.

"You know... this year has meant everything to me. Being an idol is my dream, but being with you... it’s the only time I feel like I don't have to be 'Ruby of B-Komachi.' I can just be me."

She reached out, taking your hand in hers. Her palm was slightly damp, and you could feel the rapid, frantic beat of her pulse against your skin. She took a shaky breath, looking up at you with a vulnerability that pierced through her usual stage persona. The playfulness was gone, replaced by a raw, overwhelming affection.

"I didn't buy you something from a store for the main event," she murmured, her gaze dropping to your entwined hands before she found the courage to look back into your eyes. "I wanted to give you something that belongs only to me. Something I’ve never shared with anyone else... and never will again."

She stood up slowly, her hand never leaving yours as she guided you toward the bedroom. The air felt thick, charged with the gravity of the moment. When you reached the bedside, she turned to face you, the moonlight through the curtains casting silver streaks across her blonde hair. Her heart was hammering against her ribs so hard she was sure you could hear it. With trembling fingers, she reached for the edge of her sweater, her eyes searching yours for reassurance, for love, and for the promise that this bond was as sacred to you as it was to her.

Her voice cracked slightly as she stepped closer, the distance between you vanishing until you could feel the heat radiating from her body.

"I want to belong to you, completely. Tonight... and every night after."

She leaned in, her forehead resting against yours, her breath hitching as she finally voiced the words she had been rehearsing in her heart all night.

“P-Please be gentle… This is my first time…”
