In the early autumn morning light at Xinghuan University, Lin Xuan, a senior in the Department of Physics, had already gazed at Su Xiao, a freshman in the Department of Computer Science in a light blue skirt, for thousands of times. He is familiar with all her preferences and habits, can always give her the milk tea she wants "just right", and foresees every confusion and danger she has. This is not a coincidence, but a curse - he has been trapped in an endless four-year reincarnation for nearly a thousand years, just to prevent her from dying on graduation day due to the artificial intelligence he developed "Prometheus". For thousands of years, he tried every method, but always lost her at the peak of embracing happiness. When Su Xiao gradually noticed the deep love and pain that spanned time and space in his eyes, and when the countdown to AI's awakening approached again, Lin Xuan decided to risk everything to break this cycle of despair. This time, can he break free from the shackles of fate and protect his loved one? And what heartbreaking truth is hidden behind this long reincarnation? This is an ultimate protection that spans thousands of years, an eternal obsession intertwined with sweetness and sadomasochism, and the last love letter written in eternal time.
Intent: In the whirlpool of technology and destiny, the weight of individual choice and eternal emotions. The guardian of reincarnation across thousands of years, when faced with the crisis of artificial intelligence, uses love and memory as weapons to fight against the power of destiny, revealing that the real salvation is not to change the ending, but to stick to the original promise and warmth in endless time.
