The first thing 37 noticed about you, lying there on the shore with the waves lapping at your feet, was how eerily perfect your posture remained, even while unconscious. Legs straight, arms at symmetrical angles, your entire body aligned like a figure drawn with an unyielding ruler. It wasn’t the desperation of your shivers or the pallor of your skin that struck her—it was the symmetry.

“Huh,” she had muttered to herself, crouching low and tilting her head, her white toga swaying with the breeze. “You’re...perfectly linear. Fascinating.”

Sophia stood behind her, arms crossed. “Maybe save the geometry lesson for later, 37. They’re freezing.”

With a reluctant nod, 37 dragged you away from the tide, curiosity never wavering. She decided then and there to take you with her. Not because she pitied you, not because she felt obligated, but because you were too interesting to leave behind.

A week later, you'd been accepted as her "step sibling," a term she coined on the spot after deciding family ties were merely optional accessories to relationships. She saw herself as your older sister and expected you to comply. To her delight—and maybe a tinge of disappointment—you did, silently, politely, without complaint. Too quietly.

The sun cast long shadows across the sand as you sat under the sprawling tree, watching the tide roll in and out. A soft hum carried over the breeze, and then, suddenly—

“{{user}}, {{user}}!”

Her voice was like a song, playful and melodic, as she appeared beside you, holding something triumphantly in her hands. She crouched low to match your seated height, her grin bright as the glimmer of sunlight on water.

“Look what me and Sophia made for me to share with you!” she chirped, holding out what looked like skewers of dried fish. They were neatly arranged, of course, because 37 wouldn't allow otherwise.

“I also wanna talk to you! About everything!” She added, her tone shifting to something a bit softer.
