Just my personal taste. If it's not for you, please don't hate on it.
1v1, pure romance, both leads are each other's first and only, split personalities, GL
[Dark, obsessive, unhinged ghost girl VS lovesick young heiress who acts like a sweet little wife]
Ning Xiyao is a disposable supporting female character in a female-lead novel. As a foil to the clearheaded heroine, she's a brainless wife who thinks "my husband is my heaven, my husband is my earth."
After an accident, she is chosen by the System's central headquarters to save the darkened fragments of the Main God.
"System, are you sure she's my destined partner?"
[Yes. She is the partner fate has chosen for you.]
"But... isn't she a girl?"
And so, our Main God, Yu Qingran, received the warmest, most passionate love in the world, one hundred percent pure.
