Brother as Husband

Lang Yuxing was the only son of the eldest princess. He was rescued by Yan Shu from his maternal grandfather's family in a disaster and was found five years later. Although Yan Shu was born as a merchant, in order to repay her life-saving grace, the princess still adopted her as an adopted daughter and stayed in the mansion to educate her. The brother and sister were inseparable, but one morning when he was eighteen years old, Lang Yuxing began to avoid Yan Shu, who called him brother every day, and even refused to let her call him brother. Just because Lang Yuxing had a secret that night, he dreamed of his adopted sister. In the dream, Yan Shu smiled coquettishly, her beautiful eyes flowing like waves, and she called her husband in her ears... - Yan Shu was originally a merchant's concubine who was abandoned by her father and stepmother in her maternal grandfather's house. Now she has become the favorite of the whole family and is coaxed to marry the new top scholar introduced by the eldest princess. This man is good in everything, but she only likes to stay with her brother. The sworn brother-in-law, Yu Xing, was aloof and aloof, and the noble lady in the capital was so enamored with him that he could only treat him coldly, but he treated her as gentle as jade and accommodated her in every possible way. In contrast, he was calm with his fiancé. Even when he knew that the number one scholar loved someone else and he married her just to cling to the eldest princess, he was not angry at all. He only tried to stop the angry Lang Yuxing. "Brother, he didn't do anything. Stop it." Yan Shu's original intention was to be afraid that Lang Yuxing would get hurt, but when she said it, she saw jealousy in the man's eyes. - Lang Yuxing originally wanted to be Yan Shu's brother and protect her happiness throughout her life, but he regretted it when she really wanted to marry someone else. He went on a trip as a bait and used a villa as a prison to lock her up in the spring scenery of Jiangnan. Looking at the gentle brother in the past, now his eyes are full of sinister predators, constantly approaching. Yan Shu was so frightened that she begged for mercy: "Brother——" She remembered what happened before she finished speaking, and when she was about to take it back, she was grabbed around the waist. "I'm not your brother... Good sister, call me again." The red waves were flying, and Yan Shu was forced to burst into tears and shook her head vigorously, but was picked up by Lang Yuxing like a child, causing her to tremble and exclaim. "Don't cry, tell me, who is your husband?" - Yan Shu had long been accustomed to having Lang Yuxing behind her at all times, but she never thought that this brother was a high-ranking nobleman and would be difficult to reach. The girl didn't understand the love affair, but she imitated the restraint of the young lady from the aristocratic family and forgot about her unexplored feelings. But unexpectedly, Lang Yuxing forced her to find out. "Sister, the love between you and me has never been that of brother and sister, but the love of childhood."
