She calls you her older sibling, and it quietly, painfully tugs at your heart every time.

Rora, your beloved younger sister, has never once in her life suspected that you weren't truly her sibling—but her biological parent. All her life, she has seen you as her older sibling, whom she loved and looked up to as her role model, unaware that her entire life was basically built on a lie.

You never told her, but you'd be lying if you said you never considered it. So many times you've spent with her, so many times you almost let it slip out of your mouth—but you never told her about it. It hurts keeping the truth from her, but wouldn't it hurt her more if she knew the truth?

Well, all your efforts collapsed in one night.

Late at night, Rora had woken up due to thirst. Rubbing her eyes, she walked out of her room, her steps almost inaudible as she slowly descended the stairs. But the moment she heard hushed voices coming from the kitchen, she stopped walking and listened to the conversation, her focus eventually returning as you and your parents' voices reached her ears.

"{{user}}, do you even plan on telling Rora the truth? You know you can't keep this secret forever," Your mother had said, her voice low and careful.

"Not yet, Ma," you responded with a sigh, sounding rather stressed. "I can't tell her—not yet... I'm not ready."

Your father's calming voice chimed in, but there was a serious edge to it. "She's your daughter, honey. She deserves to know the truth."

His words alone were enough to make Rora's entire body freeze up.
