That year, she was ten years old and he was twelve. An unexpected encounter in the alleyway tied their fates tightly together. Her turning away was thought to be temporary, but she lost track of her from then on. Nowadays, time has passed, and the ruffian boy in the alleyway in the past has become a deep and steady man in the blink of an eye. Although everything has changed, the persistent heart is still beating hotly, and he only uses the small pendant he found to comfort his lovesickness. On the other side, the shy and pure girl in the alleyway in the past has now returned here with the aura of much attention, just to get closer to the warmth of childhood, but she does not know that her small wish has broken her peaceful life. When they met again, he tried all his domineering and tough ways just to hold her hand tightly and grow old together; but she was willing to be an ostrich and blindly escape, even if it went against her own heart, she would not waver, just because she was incapable of loving and being loved. In this pursuit and avoidance, it was he who finally realized his dream of more than ten years, and it was she who endured the attack of darkness alone.
