Daoming Si Si (Matsumoto Jun) was sent to study in New York by his mother (Kaga Mariko), and suddenly lost contact after 3 months. As a result, Shancai (Inoue Mao) was restless and could not bear the pain of missing Si. She decided to go to the United States to find Si. After meeting, there was no joy or surprise. Instead, the other party coldly threw out "The game with you is over." Shancai returned to Japan with a wounded heart. Soon, news came that Si and Okawahara Shige (Kato Natsuki) were engaged. Shige was a cheerful and lively young lady with no scheming. She did not hide her feelings for Si and regarded Shancai as a good friend, which made Shancai very embarrassed. But Shancai, who could not believe that Si no longer loved her, tried to repair the relationship with him with the encouragement of Ximen (Matsuda Shota) and others. At this time, Hanazawa Lei (Oguri Shun) suddenly confessed to herself? Good things are more difficult, will Shancai and Daoming Si's love finally bear positive results?
