Master, My Lady's Friend Is Not a Human Being

[The sinister, yandere and short-lived male protagonist VS the cold-blooded and ruthless female protagonist who sees sorrow] Reborn as a yandere girl, Ning Shuang, she is still living a prosperous life. But what's going on with this destined marriage? He is actually a short-lived ghost who can only live to be thirty years old? Bei Mingli has a very terrible female allergy, and avoids all female animals, except Ning Shuang. As long as he is close to this woman, Bei Mingli's legs will not be weak, his eyesight will not be dazzled, he will not feel sleepy, and he will be full of energy... When we first met, "Marry me and you will have endless money!" "Get out!" When we meet again, "Marry me, and after I die you will be the richest widow in the world." "Get out... Come back..." [PS, the heroine is reborn, not time traveled]
