This is often considered a huge flaw in Serena's character, but her aimless meandering is something I think a ton of people could relate to. Many people don't really have a clear-cut path to follow, especially those who've been pushed towards very specific careers (which they don't even have any interest for) by their parents. I'm sure a lot of people, especially those from Asian families, found her struggles far more relatable than Ash's incredible confidence in his own future.
