Ask the hero in a Korean drama released by Hunan Satellite TV.

A Beautiful Day starring Yuri Song and Kong You.

When I was young, two happy brothers and sisters lost their parents because of a sudden car accident. Brother Xu Gan (Kong You) was brought to Australia by his father's driver, Uncle Qiu Jingze, and made a living by selling labor, faking marriage and even stealing and cheating. Sister Xu was adopted by a wealthy family and lived a princess-like life in North Korea.

15 years later, by chance, Qiu Jingze's son, Qiu Jingze, who stayed in North Korea, stole his wallet (played by Song Youli), found the treasured family photo, and immediately notified Xu Gan in Australia. It turns out that my sister He Na has changed her name to Park Hyun-won. Although living in a superior home, she has been living in fear and anxiety because of her yearning for her brother and her deformed love from her new brother. She felt that her life was out of her control, so she decided to run away from the family and found a job in an aquarium.

In the aquarium, Jiang Donghe (South), a gentleman, humorous, handsome and always smiling in his eyes, has always paid little attention to the girls around him, but he was attracted by this new hourly worker. He found that this smart and beautiful girl, strong and capable, loves to laugh, and there are many puzzling mysteries in her life. Driven by strong curiosity, he became more and more fond of henna. ....

Xu Gan, an Australian brother, and his uncle's family are not rich, but they have established a deep affection for each other. Jingze's daughter Xiaozhu (Li Yanxi) has long fallen in love with Xu Gan, but because she has a very serious heart disease and needs surgery, her life is in danger at any time, so Xu Gan even risked her life to raise Xiaozhu's surgery fee, but she still failed. After getting the news of the whereabouts of his new sister Henna, Xu Gan resolutely decided to go back to South Korea, on the one hand, to see the lost sister 15, and on the other hand, to raise the operation fee for Hyo-ju through the rich sister's house. It turned out that Xu Gan, my brother, had long known that his sister Henna was not her own sister, but was brought home by her stepmother when she remarried. But this naive and lively, timid and clever girl has always been deeply loved by herself, and she is so inseparable. ....

One day after returning to Korea, Xu Gan came to the window of Henna's house with anxiety and excitement. He met his sister who fell from the sky and hit him. It turns out that my sister is also preparing to run away and start her own independent new life. But Xu Gan dare not presume to recognize her sister. Will this slim and timid sister recognize herself? Will you still recognize this treacherous brother who promised to come back and clean himself up, but has broken his word? Holding hands in the cable car and dressing in the sightseeing hall can awaken her sleeping memory?

Park Tae-won, the son of Park Chun-quan, president of Daxian Group, was jealous when he saw his foreign sister He Na take the place of her dead sister Huiyuan, taking away all her mother's love. However, this smart and distressing sister made him unable to stand being treated badly by others or being treated well by others. With deformed love, Park Tae-won brought He Na home with ulterior motives and tried to be violent. Fortunately, she was saved by Xu Gan who arrived in time and was severely beaten. At this time, I finally awakened my sister's memory and intuition. Who cares so much about protecting themselves? Isn't it an agreement to come back and miss your brother day and night? Yes, it must be him. 15 years of waiting finally stopped at this moment, and brothers and sisters hugged each other tightly.

Xu Gan took his sister back to my uncle's house. Xiaozhu knew that the brother and sister were not related by blood, and Xu Gan didn't love herself. She is nervous and unwilling in all aspects. Although Xu Gan brought his sister back, he didn't forget his other mission, which was to raise money for Zhu Xiao's operation. This person seems to be his other sister, so he continued his plan. He and Cheng Can found Park Zhenquan and asked for a job in the company. Uncle Qiu Jingze, after seeing Park Zhenquan, accidentally recognized this familiar face as a colleague who had an affair with Xu Gan's father, President Xu, but Park Zhenquan seemed embarrassed to admit that there seemed to be something hidden in it.

One day, when Xu Gan came home, he saw Park Tae-won driving away with Lotus and hurried to catch up. Tae-won made a mistake in his busy schedule and pulled into the side of the road. Suddenly, a strikingly similar scene appeared in front of Xu Gan. It turned out that Xu Gan's father, President Xu, drove home one day on 15 and saw Park Chun-quan driving away. His wife sitting in the passenger seat knocked on the window for help anxiously and helplessly, so she hurried to catch up. Park Chun-quan was desperate and caused the car to turn over. Young Xu Gan saw his father get off the bus to save his mother who was injured in the car accident, but with a loud noise, his parents were swallowed up by a raging fire. In the twilight, he only saw Park Chun-kwon's frightened face, which escaped from the car in a hurry. Xu Gan suspected that Park Chun-quan was the murderer who deliberately murdered his parents and robbed the Xu family's property, so he retaliated against Park Chun-quan. But bigger secrets are still being exposed. From Park Tae-won's mouth, he learned that He Na was actually the biological daughter of Park Chun-quan, the father-killer, and not just body double, the daughter of Park Huiyuan who died young. This bolt from the blue overwhelmed him and was unacceptable. He doesn't know what to do, because he loves Henna deeply, and Henna knows the truth, but he can't and dare not confess to each other. Looking at Henna, she accepted Jiang Donghe's love in desperation, but unreasonably opposed and blocked it. ...
