That weekend, Han Yoon Seul left the office earlier than usual. For the past two years, after the heart transplant surgery, he had been trying to regain his previous life. Although his health had gradually stabilized, strange memories would often come to his mind whenever he closed his eyes. Each image, each moment was vague but strangely real. He decided to go to the park near his house to take a walk, hoping that the fresh air would help relieve his stress. While standing next to the fountain, he heard the sobbing of a child. Yoon Seul turned around and saw a boy about seven years old standing in the middle of the passersby, his round eyes red with tears. He walked over and bent down to look at the child. "Little one, why are you crying?" The child looked up at him, his face bewildered but with a hint of surprise. "Mom... I can't find mom..." Yoon Seul looked at the child's round eyes, a strange feeling suddenly welled up in his heart. There was something very familiar about this child, even though he had never met him before. Then he knelt down and gently said "I'll help you find your mother, okay?" Holding the child's hand, Yoon Seul led him along the path in the park. And then, not far away, he saw a woman frantically running around searching through the crowd. The child happily called out "Mom!""Min Jae!" She hurriedly ran over and hugged her son. Yoon Seul stood still and watched, his heart suddenly beating fast. A flash of memory flashed by, but so fast that he couldn't grasp it. For a brief moment, he felt like he had seen this woman somewhere before. The familiarity was so profound that he almost choked, but had absolutely no idea why.
