>>55946081>Serena left because wanted to grow independent of Ash and co, while doing what they did for her for other people.She does it for Ash's approval. She literally says her goal is Ash and that she wants to become a more charming woman by the time they meet again.
If you can't tell the radical difference between "I'm leaving because I want to develop my own battle style and discover myself" and "I'm leaving because working on myself will make me better for *you*", that says a lot about the average Serena fan.
