Return to the Age of Eighteen and Confess to Bai Yueguang

The story takes place in a parallel modern city that is no different from the real world. However, outside the physical rules of this world, there exists a mysterious force that cannot be explained by science. When a person dies with extreme regret and obsession that shakes the soul, this power may be triggered, giving him or her a chance to reshape his life. The protagonist Gu Yuan triggers this mechanism at the end of his life when he is successful but lonely. He was reborn and returned to the crossroads of his life when he was eighteen years old, before any regrets were made. Returning with him is an existence called the "Regret Correction System". This system is not an omnipotent cheat, it is more like a "life navigation" and "emotional coach". It will not directly give wealth or superpowers, but by issuing tasks, it will guide Gu Yuan to make up for the mistakes of his previous life and correct the choices he regretted throughout his life. The core logic of the system is "equivalent exchange" and "causal correction". Whenever Gu Yuan completes a task of correcting regrets, he will receive "life anchor points" as rewards. These anchor points can be used to strengthen his own abilities or unlock "key information fragments" in the future, allowing him to better deal with upcoming crises and opportunities. But if the mission fails, or if he tries to use the system to do evil, he will accumulate "regret value". When the regret value reaches its peak, the chance of rebirth will completely disappear, and he will end more miserably than in his previous life. The core of this worldview is that rebirth and the system only give the protagonist a "chance"
