What did Gossip Girl say in the first part?

Generally speaking, the plot of this TV play is very chaotic. Basically every star is connected. Anyway, everything that can match together is matched. The synopsis of the first season has recently begun to spread in the aristocratic preparatory schools in new york's rich areas-Serena van der Wooderson (Blake Lively) is going back to new york. The source of this news is the well-known but super mysterious "Gossip Girl" blog-I don't know why, this "girl" knows every move of rich children like the back of her hand. No one knows the true identity of "Gossip Girl", but in this complex circle of rich children, everyone relies on her mobile phone text messages or online messages to get first-hand exclusive information. These people are addicted to "Gossip Girl" and can't quit, which has become a vicious circle. Blair is Serena's closest friend. When she saw Serena suddenly ending her "self-exile" in boarding school and returning to Manhattan, she was as surprised as everyone else. She even had a conflict with Serena. The tension between Blair and Serena has not affected the power of Gossip Girl. She seems determined not to stop until she reveals the truth of the scandal-what scandal is it? Does it have anything to do with Serena's brother Eric, Blair's boyfriend Nate and Nate's best friend Chuck? Or is it about Dan and his sister Jenny? Dan and Jenny grew up in a middle-class family, but they couldn't integrate into this small group of wealthy upper class, so they could only wander in the "marginal world". Is the truth of the matter related to parents? Serena's mother Lily used to be a photographer. Nate's father Howie archibald is a very powerful man; Dan and Jenny's father Rufus used to be a rock star, but now he has turned to an art gallery. Recently, parents found that their children often watch mobile phones and read the latest news and gossip from Gossip Girl. Parents began to wonder ... among this small group of rich children full of false friendship, jealousy, chaos and complexity, the biggest secret is still unknown-who is Gossip Girl?
