[Reporter Liao Lihui/Report from Taipei] Chinese actor Dong Sicheng has recently attracted attention for his performance as the aloof schoolmaster in "Today is Sun Rain". Many people describe him as "explosionally popular", but in the eyes of the Korean group fans, they can't help but smile bitterly, because He has long been popular as a member of the Korean group NCT's sub-unit "WayV". Now his popularity has reached a higher level due to his performance in dramas. Some fans of WayV laughed at themselves: "WINWIN (Yunyun) has been working in vain these past few years!"

Dong Sicheng was born in Zhejiang on October 28, 1997. When he was a student, he was followed by a sister outside the High School Affiliated to the Beijing Dance Academy. It turned out that she was a talent scout for SM, and he didn't know if he could take a photo of her. Dong Sicheng thought that the other person looked pretty good, so he took photos of her and went to SM Entertainment during the summer vacation. Later, he was admitted to the acting department of the Central Academy of Drama, but he still decided to become an SM trainee in his freshman year.

He debuted as "SM ROOKIES" in 2016 and debuted as "NCT 127". He can also be seen in NCT U's hit song "BOSS" in 2018. In 2019, he debuted as NCT China's unit "WayV" and achieved good results. He announced the establishment of a personal studio in China in September 2021. Although he is still a member of "WayV", he later clearly focused his career on drama performances, and has successively performed in many Chinese dramas, including "Returning at Midnight", "Five Blessings", "Good Chen Meijin" and so on.

Because he stayed in China for a long time to develop, he was too focused on drama performances, and the attendance rate of group activities dropped sharply. His "not doing his job properly" caused dissatisfaction among some fans, who criticized him for being the "actor", so he was often called the "actor".

As expected, he announced the expiration of his contract on July 8, 2026, and officially quit NCT, ending his 10-year relationship with SM Entertainment. His farewell letter was sincere, saying that over the years, he has gradually become clear about the direction he wants to go in the future, "Balancing film and television and the stage, calm down and slowly polishing my own works. After repeated weighing and careful communication, I finally reached a friendly consensus with the company."

Now he is attracting attention for his role as Chen Yanzhou in "Today is Sun Rain". He is partnered with Yang Chaoyue, who is also from a girl group. The number of views reached 200 million in the first three days. His hard work has paid off, which makes many fans very happy.
