Su Momo tried to take her life several times after Lang Xingchen death. Meanwhile, Lang Xingchen who was about to reincarnate saw this scene and made a decision. Lang Xingchen is willing to sacrifice her reincarnation just to protect her lover by erasing Momo's memories. Unfortunately (?), Su Momo still fell in love with Lang Xingchen who became a spirit.

After Lang Xingchen spirit disappeared, Su Momo later diacovers that the lover of Lang Xingchen was actually her. She decided to remain single.

One day, Su Momo is watching the Moon until the Moon became bloody red. She knows that the world will end, but she's still quite happy (I think).

Then, she suddenly woke up and saw Lang Xingchen beside her. The world restarted from the time before Lang Xingchen died. She prevented it, and they lived happily ever after. It's a bittersweet ending because this time, Su Momo is the only one who remembers. (The author said that Mu Rong, a character from the other novel, sacrificed her body because an evil character will take advantage of the bloody moon. Then, the world restarted.)
