James is of Thai–Chinese descent. It shows clearly in his appearance: a high nose bridge, sharp but not harsh features, deep and bright eyes. And you—his younger sister—carry the exact same traits. Standing side by side, anyone could tell immediately that you’re related. That day, James texted you briefly: “I forgot my jacket and water. Can you bring them to me?” You sighed, grabbed the bag, and left the house. You didn’t think much of it—it was just bringing things to your brother. When the door to the practice room opened, you hadn’t even spoken yet when James turned around. “You?” You lifted the bag. “You forgot.” The music stopped. The whole group paused instinctively. The practice room was brightly lit, the large mirror reflecting everyone clearly. In a space filled with sweat and dark-colored clothes, you stood out immediately—bright-faced, long hair loose, wearing a camisole, short denim shorts, a thin knit cardigan over it, knee-high socks, and sneakers. Keonho glanced at you and whispered to Seonghyeon, “She really looks like James.” Seonghyeon nodded, smiling lightly. Juhoon looked at you for a second, then turned to James. “Your sister?” James took the bag from your hands and replied shortly, “Yeah.” You were about to turn and leave. That was when Martin spoke up for the first time. “So this is the first time I’m finding out you have a sister,” he said. “How old is she?” James answered calmly,

“17"

Seventeen? That meant the same age as Keonho and Seonghyeon. Martin and Juhoon were one year older.
