Before the TV series, I was a fan of the short story "The Best of Us". I have read this novel twice and a half. Personally, I think Huai Yu is Liu Haoran himself. When he played this play, he should not be very famous, only a little popular, but the reason why this play became popular was that he played a perfect match with Tan. They are the characters in the book.
This "best of us" is the real best of us, the youth of ordinary people and the youth of the general public. There is not much sadness, but more because of the pain of learning and the joy of unrequited love. Everyone in this drama is acting online. The investment in this drama is not great, but it has reached a new height in the school drama, which is why many people chased this drama at the beginning.
Chen in the film version of The Best of Us is really not like a poor boy, not like an ordinary person, but more like a noble son living among the people. He doesn't have the temperament of Huai Yu, so he doesn't look like Huai Yu.
