Which episode of Shiny Tomorrow has a sex scene?

The 48th Integrated Wind has something to do with Sun Yanran.

The whole family is actively preparing for the marriage of Tang Zhenghao and Du Xinyu. Broken-hearted Chengfeng drinks in the boxing gym, and then Sun Yanran sends the drunk Chengfeng to a nearby hotel. After Chengfeng was arranged, Sun Yanran wanted to leave, but Chengfeng suddenly grabbed Sun Yanran's hand and said he couldn't leave her. The next morning, Cheng Feng found himself having sex with Sun Yanran. Sun Yanran told Cheng Feng that although he liked him, he wouldn't have sex with him in this way on purpose. We are all adults, so we don't have to take this night seriously, but if Chengfeng is really willing to take care of her one day, he will come to her again. Ding Yirou met Tang Zhenghao and Du Xinyu in the teahouse. She excitedly went up to Tang Zhenghao to confirm whether he really wanted to get married, and Tang Zhenghao replied yes. Ding Yirou, who had a nervous breakdown, asked Tang Zhenghao why he would rather choose a cripple than her. Tang Zhenghao immediately changed his face and warned Ding Yirou to keep his mouth shut, otherwise they would not even be friends. Ding Yirou said that her father died with her mother. Over the years, Tang has been the support of her life. When Tang Zhenghao came to the cemetery, he told his mother that Ryan wanted to marry the daughter of his enemy, hoping that her mother would forgive his decision. Ding Yirou heard Tang Zhenghao's words not far away. She didn't expect Du Xinyu to be the daughter of the murderer who killed Ryan and her father. Tang Zhenghao had a video call with his aunt yu zhen. He told yu zhen that he was getting married and invited yu zhen to the wedding. Seeing that his bohemian nephew has a home, yu zhen is very happy for him. Before hanging up, Tang Zhenghao said that he hoped his aunt would stop looking for the real murderer who killed her mother. He hoped that the discord would end there. Aunt said Tang Zhenghao could forget it, but she wouldn't forget it. She can't stand the person who killed her sister getting away with it. The conversation between Tang Zhenghao and Furong was heard by Ding Yirou. She thinks that if Du Xinyu is the daughter of the murderer who killed Ryan, Jade Furong won't let them get married. Ding Yirou went home to check the information about the fire. Not only that, she also sneaked into the personnel department and got Du's information. Before marriage, Du Xinyu took her mother and brother-in-law to visit her in-laws in Tangjia. She happened to meet her granddaughter and Sun Yanran who came to visit the Tang family. Grandma recognized Wang Zhi, a part-time worker, at a glance. After learning that Wang Zhi's job was part-time, her grandmother changed her face. Du Xinyu said that her mother and daughter had been selling salted eggs for a living, but later Wang Zhi had to take a part-time job to help her raise the tuition fee for resuming school. After listening to her explanation, her grandmother was a little distressed by Du Xinyu.
