Huo Shan is a degenerate young man in the 21st century. Although he longs for sunshine, he cannot get rid of the pain in his heart. He wants to be redeemed by loving and being loved, but he cannot fall in love with others and cannot believe that he will be loved. With the mood of "the only one I can love is myself, and only myself can love me" and "only if you love yourself, you will not suffer or be bound", Huo Shan lives a false and tense life. . . It wasn't until one day that he found himself somewhere in the future of human life, and he breathed a sigh of relief deep in his heart, thinking that everything was over, but he didn't know that everything had just begun. . .
