Lying in a pool of her own blood, Yun-ji strained to see the blurred figures of a man and a woman. Their faces became clearer as they drew closer. The man held the woman's hand, smiling warmly at her.
"I really pity you, dear sister. But it's your fault for thinking you could be part of the Choi family, enjoying privileges that belong to me." The woman sneered, her voice laced with malice.
"She doesn't have much time left, my love. Before her end, she deserves to hear the good news," the man said, his smile never faltering as he looked at the woman.
The woman giggled, her eyes cold. "Yun-ji, we're getting married soon. I bet you didn't know that. In fact, we've been together from the beginning. You were just a stepping stone for us. You were useful, for an orphan—so talented. We used your skills to make a fortune. But now that you're no longer useful… goodbye."
The man added, "One more thing, Yun-ji. Your real family is extremely wealthy and loves you deeply. When they see the letter you signed, the one saying you wanted your 'sister' to have everything that belonged to you, I'm sure we'll have a fortune." The man she had once called her fiancé turned to her sister, gazing at her with an affection he had never shown Yun-ji.
Yun-ji's mind raced as their words cut deep. Questions overwhelmed her. *Who is my biological family? Why did they abandon me? If they love me, why haven't they found me?*
The pain surged again, bringing her back to the harsh reality. Her dress was soaked in blood from the accident. She glared at them, her eyes burning with fury and a vow to seek vengeance. If she were given another chance, she would find answers—and make them pay. Her consciousness faded, and soon her body lay still.

The winter breeze swept through the streets, biting and sharp as it cut through the air. It whispered through the cracks of old wooden windows, filling the room with a chill that seemed to sink into her bones. The wind, crisp and relentless, carried the scent of snow and the echo of a silent, frozen world.
Yun-ji winced as pain surged through her body. Her legs throbbed, and her head felt like it might explode. Her eyes fluttered open, trembling from the effort. As her vision cleared, she saw a familiar sight—a tattered study table holding an old-fashioned desktop and a small diary. It was her old room. She remembered it clearly.
Her gaze moved around the room, landing on a small cupboard. Everything was as it had been back then. It was as if she had returned to the Choi family house where she had lived until she graduated. Shock rippled through her as she looked down at her body—small hands, slender legs… even her chest was flat. She gritted her teeth against the pain and slowly forced herself to stand.
When she reached the mirror, she froze. Staring back at her was the face of her younger self, the same appearance she had in high school.
Her eyes landed on the diary on her desk. It had a worn pastel blue cover, its edges soft and frayed from years of use. Faint doodles and tiny stars decorated the corners. Across the center, handwritten in bold, slightly faded ink, were the words: *Yun-ji: Senior Year of High School.*
