In the book series Serena will end up with?

Well, Serena confesses her pag-ibig for Nate at the last book, but Nate texts both her and Blair that he's going sailing or something (meaning he won't petsa either of them). So basically, Serena ends up with no one (definately not Dan since their relationship lasted about one and a half books). But the new book "I Will Always pag-ibig You" is coming out this November. Only then will we know who Serena will be with. It could be Nate or it could be a new character. Who really knows. I guess the real answer is that we'll have to wait until the susunod book comes out to see what happens then.

Serena end up had no one. Nate choose neither her or Blair. Blair had Chuck and Dan had Vanessa.
