[Quickly travel through time, a yandere hero, love at first sight, a two-way journey, sweet love, a stunning heroine, and the original heroine's regrets] In some worlds, the heroines are insane, yandere, and possessive. The heroines call them demons! These heroines often face critically ill parents, bankrupt companies, and son-biased parents. They need the hero's help, yet fear his possessiveness. They want to escape, but are constantly "forced" to return to him for various reasons. In some rebirth stories, the heroine only discovers who truly loved her best until her death, leading to the collapse of her small world and the weakening of the laws of nature. Before their death, these heroines vow, "If there's a next life, I will love the hero well." The heroines of these small worlds, swayed by the plot, become entangled with the heroines. The heroines resent their maniacal, morbid love and the perverse possessiveness of these yandere heroes, leading to a love-hate relationship. Yun Qiyue has a special fondness for these yandere heroes, sympathizing with their unrequited love. Since the heroines suffered so much from being loved in their previous lives, she decided to let them love them.
