Confusing

(I haven't abandoned the update. I haven't written a novel for a long time. I'll open a new one and try it out before coming back. 5.1) The story of my brother, the new article "Variables" please give me advance notice. The next door "Transport into the Mary Sue I Wrote (Quickly Travel)" is being serialized. The copy is below the copy of this article! * Copywriting of this article: Ruan Ningchu is not very young, but she has black hair and red lips, a pair of passionate eyes full of water, and a slim waist. Almost everyone who has met her will not praise her beauty. There was only one person who not only ignored her beauty, but also threw a woolen coat for her to put on, saying, "It's cool in the night." Ruan Ning, who had just returned from disco dancing in the bar and deliberately wore a red suspender sequin skirt, first looked at the room temperature meter on the wall that showed 36°C, and thought to herself: This person is probably trying to heat her to death! However, she paused for a moment, wrapped herself in her woolen coat, and tried her best to put on a charming smile. Alas, why did she like such an old-fashioned person? * Gu Chen, a professor at Peking University, is a man of few desires and does not understand amorous feelings. He has a handsome face for nothing, but there is not even a person of the opposite sex who comes close to him. His fraternal friend was sent abroad by his company. He was worried about his innocent and lively sister who had no life experience and asked him to take care of her for three months. He frowned and refused, "Aren't you afraid that I might steal something from you and eat the grass on the edge of my nest?" After hearing this, my friend laughed loudly, "Not to mention that my sister has just graduated from high school. You are one year apart in age. You would never do such an animal thing. Not to mention that you are not sexually attracted to women at all. In your eyes, the female mice in the laboratory are more attractive than my sister!" Gu Chen thought so at first, but later he discovered that Ruan Ningchu's every move could make his throat tighten. As above, the female protagonist is 18 years old and the male protagonist is 30 years old. [Fate update] [Screenshot taken on 2021.12.11] Thanks to the kind-hearted wife of Bishui for the cover! ————Dividing line————"Variables" Please receive advance payment! Copywriting: When Murong Pingting met Ruan Hengyi again, it was at a banquet hosted by her family. Although he has obviously worked in Africa for four years, he has not even tanned. His skin is paler than that of many girls, and he is also quite eye-catching in the crowd. The banquet was called a birthday celebration, but it was actually hosted by her parents who selected a rich husband for her. There were many handsome and handsome young elites among the invitees, but she always felt that something was missing, and she couldn't be interested at all. Until she saw Ruan Hengyi, she suddenly had an idea. She went over with a wine glass and asked with a smile, "Brother Hengyi, there is a deal. I wonder if you are interested?" She and Ruan Hengyi were childhood sweethearts. They knew each other well. The most important thing was that the other party was very good to her sister. When she was young, she envied Ruan Ningchu, the person next door, who had a very good brother. It's a pity that her parents are not willing to have another child besides her, not to mention an older brother, not even younger siblings. However, if she marries Ruan Hengyi, then someone else's good brother will be hers. * Ruan Hengyi has always focused on the two most important things in his life, one is to take good care of his sister, and the other is to revitalize the Ruan family. He pays little attention to other things. I don't know since when, my sister Ruan Ningchu often mentioned Murong Pingting, the good sister from next door, and he couldn't help but focus on this younger sister Pingting. However, although his sister Chuchu no longer needed his care, the goal of revitalizing the Ruan family had not yet been achieved, so he could only suppress the throbbing in his heart. Until they met again, Murong Pingting proposed a deal to him. She lacks a suitable marriage partner to take care of the family, and he lacks funds to expand into new markets. Murong Pingting said to him, "A gold mine has just been discovered in the barren mountains of my home. Marry me and I will give you the gold mine. Do you want to make a deal?" Ruan Hengyi smiled, his original restraint was completely destroyed, his eyes were full of possessiveness, and he said, "Okay, I can't get it." From then on, the two most important things in his life seemed to have remained the same, except that he had a sister, Pingting, and the Ruan family also had his wife Murong Pingting. * Although there is only a relationship similar to that of brother and sister, this kind of marriage feels good. ——Murong Pingting You are the only variable in my life. How could I just be your good "brother"? ——Ruan Hengyi Love after marriage, secret love comes true. Intention: Love melts icebergs
