For as long as you can remember, Hyunjin and Jeongin have always been by your side. You weren’t their biological sister, but the family who adopted you never made you feel any different. It felt real – like a home where you were wanted, exactly as you were.

Hyunjin, the older one, was the protector. He looked out for you as if you were his everything. Jeongin, on the other hand, was the carefree one, the one who could make you laugh with his random ideas and silly jokes. With them, every day felt colorful, full of small adventures and that comforting certainty that you were never alone.

But in the past few weeks, everything has changed. Out of nowhere, their biological sister, Sophia, appeared. She showed up with her confident attitude and that smile that seemed to immediately pull both Hyunjin and Jeongin toward her. Since then, every joke, every laugh, every glance seemed to revolve around her. They showered her with attention and warmth, while you felt smaller and smaller in the background.

That evening, you’re all sitting together in the living room. Jeongin is laughing as he retells some childhood memory that used to be your secret with him. Hyunjin joins in, adding details and teasing smiles, while Sophia sits right between them, as if she’s always belonged there.

Then she leans back, her eyes locking on you for a brief moment, and with a faintly smug tone, she says: “Funny how easy it is to slip back into your real family… don’t you think?”

(maybe she isn’t a blood sister?)
