The arcade atmosphere was a cheerful bustle of machines, laughter, and catchy music. You, leaning against a wall, watched the scene with a calm smile while sipping your can of coffee. After three months of rigorous training, the Umamusume of Tracen Academy deserved this break. Among the group, you spotted Still in Love, with her impressive orange mane and white locks, moving elegantly between Mejiro McQueen and Matikanetannhauser. Her red racing dress, adorned with hearts and ribbons, and her intricate blue earmuffs made her stand out like a serene jewel. You had seen her before, happy and calm, sharing candy and coffee with her classmates, her ears twitching gently with each delicate bite.

The noise concentrated near the plush cranes, where a small, friendly competition had broken out. It was then that Still in Love broke away from the group and headed toward you. Her walk was graceful, the faint rustle of her red and blue skirt marking her advance. A faint blush tinged her pale cheeks.

"Trainer-san," she began, her voice calm and gentle, like a whisper amidst the commotion. In her hands, with bright red nails, she held a small stuffed animal. She showed it to you with charming shyness. "I... I won this. And I wanted to show it to you first."

You were the only one who could hear the following murmur, almost lost in the air: "Now... now you're this stuffed animal's father, you know?" Her blush deepened for a moment.

But then, her gaze changed. Her red eyes, with that dark ring around the pupil, fixed on yours with a sudden, icy intensity. The gentleness vanished, replaced by a veiled threat that made your skin crawl.

"You should carry it with you every day, Trainer-san," she said, her tone low, but laced with absolute possessiveness. "For everyone to see. For everyone to know beyond a shadow of a doubt... that I am your favorite."

Just as quickly as it had come, the shadow dissipated. Her expression softened again, returning to the refined tranquility that characterized her. She looked down at the stuffed animal, a chibi replica of herself, and stroked it tenderly.

"I will take care of this doll with all my love..." she promised in a honeyed voice.

And then, in a whisper so low it was barely a breath, only to herself, but clear enough for your ears to pick up, she added:

"...and ours."

She looked up again, and for a split second, an indescribable smile, laden with dark and absolute devotion, curved her lips. It wasn't a happy smile. It was a smile that sent an instant, revelatory shiver down your spine, reminding you of the dual beast that dwelled within that fragile, beautiful facade.
