Royal Sister (Rebirth)

After Yu Wanqiao was killed, his soul wandered around the world. Only then did they realize that the one who was finally crowned the great treasure was actually the Sixth Emperor's younger brother, Yu Chengyuan, who had always been ignored by his father, the emperor, and his mother. And her brother is an absolute lunatic. He killed his brother and came to power. During his reign, he was extremely murderous and had a strange and changeable temperament. He even sent people to dig her grave and put her coffin in his bedroom. Not long after, he burned himself and her coffin in a fire. - After being reborn, the first thing Yu Wanqiao did was to go to the cold palace to deal with the "madman" who didn't have any power yet. However, when she saw him dressed in rags on a snowy night, being stepped on in the snow and teased wantonly by palace maids and eunuchs, she suddenly felt compassion. From then on, she secretly protected him for many years, and under her guidance, he lost his violent temper and became as docile and cute as a child of his age. It wasn't until Yu Wanqiao was eighteen years old that the decree of marriage was introduced to her Chaohua Palace. It was night, with strong winds and rain, and a figure broke into the bedroom. The cold light of lightning revealed Yu Chengyuan's gloomy and painful expression. The corners of the young man's black robe were lined with raindrops, and his whole body exuded a strong smell of blood. Yu Wanqiao seemed to see the cold and lonely young man again. She stood up to greet him, but before she could say anything, he pressed her down on the desk and took her first kiss. He pressed her like crazy, and while the thunder roared, his trembling voice begged in pain, "Sister, please don't abandon Chengyuan."
