This is a campus sadomasochism story about two male protagonists about redemption and self-healing. Yu, the top student in science, was "reborn" and returned to the second year of high school. In order to make up for the regrets of his previous life, he resolutely transferred to Class 13 of liberal arts and cautiously approached the young man Chen Yuxing who was covered in thorns. On the surface, it is Yu You's gentle protection and redemption, but in reality it is a carefully woven dream - in reality, Chen Yuxing suffered a mental breakdown after Yu You jumped off the building. Three years later, he created a novel simulation program in the junior year laboratory, based on the abuse novel "Wu Xin" he wrote, and imprisoned himself in a virtual world to sleep for three years. The "Yu You" in the program is just a little consciousness of the real Yu You that remains in the computer, but he thinks that he has returned from rebirth. When the truth is revealed, two sober and painful souls confront each other in a program that is about to collapse, and ultimately point to the profound idea that "only by learning to love yourself can you truly love others."
Purpose: Love others, love yourself, and learn to reconcile with yourself through loss and reunion.
