When he met her, he was fourteen and she was thirteen. She had moderate autism. Her grades were good, but her behavior was strange. Despite being mocked by everyone, he fell hopelessly in love with her. Growing up in a family torn apart by his parents' impending divorce, he was saved by her as they spent time together, and she put him on the right path in life. As time passed, she steadily recovered and became more like a normal person. They were admitted to different high schools and forced apart. When she realized she was ill, she consciously rejected his affection. In pain, he tried to find her and pour out his feelings, but to no avail. While searching for her, he ran into her best friend, who was also his classmate: a beautiful girl with a tragic past. She became deeply jealous of the passionate love he felt for her friend. They met by chance, and he loved her devotedly, swearing to protect her for the rest of his life. Then, after the college entrance exams, she seemed to vanish from the face of the earth.
Years after they parted, they met again and came to know each other through work. Faced with career setbacks and hardships, the two people who had once saved each other found their way back together to weather life's storms. In the end, they loved but could not be together, and once again turned away and disappeared from each other's lives. Yet, with their most sincere blessings for one another, they continued to watch over each other from afar.
