He would marry her, but later on, he was pressured by his family, society, and so on. In the end, the two of them separated and had a heartbreaking ending. Any recommendations?

The title of the novel was very similar to Ink Dye Falling Flowers, both of which were sadistic. The male lead and the female lead had known each other since they were young. The male lead had even promised the female lead that he would marry her when he grew up. However, the male lead had mistaken her for the female lead. Then, the female supporting role fell ill and needed the female lead to be the drug primer. Then, the male lead proposed a marriage alliance with the female supporting role's father. On the wedding night, the male lead used a candle to pierce the female supporting role's hymen because the female supporting role's blood could be used as the drug primer and the female supporting role's illness could be cured. Then, the female supporting role was the female lead's sister, White Lotus…After that, the male lead kept abusing the female lead. At the end of the introduction, the female protagonist kept beating and scolding her because the male protagonist didn't know her, and then jumped off the city wall. The male protagonist also mistook the female protagonist at the end of the introduction. When he learned that the female protagonist jumped off the city wall and died, he poked his own eyes and said," This pair of eyes didn't recognize you at the beginning, what's the use of having them?" When I first saw the introduction, I only read a little and stopped reading it. Now, I want to read the title. No, no, it didn't look like Ink Stained Flower, it looked like this: He grabbed her hand and threw her to the ground Lin Cai Wei Lian Er is back, I don't need you anymore Oh, right, I still need your blood as a drug primer for Lian 'er.

Because the antidote was too strong, she needed someone to drink it first and then use that person's blood as the drug primer.] Someone bring me the medicine Lin Caiwei drank the medicine and her stomach hurt, but she just bit her lower lip stubbornly and refused to make a sound. In the end, she couldn't stand it and snorted. In the end, Lin Caiwei fainted from the pain. Until the next day, I saw the injury on my right hand and smiled. She thought about how he was still in Yunlai's arms a few months ago and now At this time, Yunlai came again With medicine in hand Lin Caiwei drank the medicine without looking at Yunlai. And then there was endless pain And this time she vomited blood, not like before, but vomited large mouthfuls of blood He sent for the imperial physician Hurry, if you can't cure it, you don't have to stay in the palace anymore. She smiled. In the end, it's still for her. If she dies, who will be the drug primer for his Lian 'er? And then I passed out Emperor, the Empress's health is not good.
