Shen Yingwan, a graduate student in criminal psychology, is afraid of all reflective surfaces due to her childhood shadow, but she is pulled into the Mirror Realm and becomes a player. Here she meets Lu Wangshu, a photographer who can "see" the color of emotions. The two went from testing each other to relying on each other, and approached the truth in mirror nightmares - the mirror realm is expanding, and the price of closing it is that someone must stay in the mirror forever. In the end, Shen Yingwan chose to stay, but Lu Wangshu walked into the mirror to accompany her. The two stayed together in the eternal mirror world. From then on, in the deepest part of every mirror, there were two figures reflecting at each other.
Purpose: We will eventually reconcile with ourselves in the mirror
