A Korean romance movie about a couple who were abroad. For some reason, the male lead returned to Korea and fell in love with his girlfriend's sister.

The female lead went on a trip together. The male lead did not follow because of a misunderstanding. However, the male lead accidentally discovered that he liked the female lead during the trip. He decided to return to the female lead. The female lead also discovered that she also had feelings for the male lead. The two finally came together.

I can recommend two novels to you. Both are about the female protagonist who returned from studying abroad, and the male protagonist is based in China. The first book was "I Love That Female CEO." After Qin Yimin returned from abroad for ten years, she met the man she couldn't forget and developed a relationship with him. The second book was "The Adorable Marriage: A Naughty Wife Drags Home". The female protagonist, Yan Sheng, was betrayed by her childhood sweetheart and stepsister. However, she met Lu Hanchen and saved her from the darkness. The two of them experienced life and death together. However, after Lu Hanchen's fiancée returned, Yan Sheng fell into darkness again. Five years later, when Yan Sheng returned to China, she became even more beautiful and confident. She even brought a cute little bun with her to pursue her own happiness. I hope you like my recommendation. Muah ~

The main character of an urban novel was invincible abroad, but there were so many people who were better than him when he returned home. 1. The difference in cultural and educational background: The male protagonist of the urban novel may have received a top-notch education abroad and obtained a lot of advanced knowledge and skills. However, the cultural and educational background in China might be different from that in other countries, resulting in the male protagonist's lack of experience and knowledge in certain aspects. 2. Pressure of competition: The male protagonist of an urban novel who is invincible abroad may face competitors from all over the world. In China, the male protagonist might face more competitive pressure and need to adapt to society and the competitive environment again. 3. Social changes: The male protagonist of the urban novel was invincible abroad, but he might have neglected the changes and development trends of the domestic society. The changes in society and industry in China might make the male protagonist outdated or unsuitable for the domestic environment in some aspects. 4. Personal growth: The male protagonist of the urban novel may be invincible abroad, but he may lack the warmth and interpersonal relationships of the domestic society. This may cause him to need to re-establish interpersonal relationships and adapt to social rules in China. The above are just some possible reasons. The specific situation still needs to be analyzed according to the plot of the novel and the author's setting.
