Couples in the book! I'm curious,please tell me,if Ты read them!

In the books, so far, Serena and Blair end up alone.
Nate had to choose between them both countless times,
he realized he loved them both too much to choose one.
So he ended up alone too

Blair and Serena meet at Grand Central, where Serena confesses that she told Nate she loved him. Before the train to New Haven leaves, they both receive a text message from Nate, saying that he loved them both and was going to sail with Captain Chips around the world. Instead of fighting with Serena, Blair laughs, and says that this was an ending they never expected.

the main couple is Blair and Nate!!
