Pokemon Amourshipping:Who said I'll never come back?

Prologue:

Ash was laying down on his bed, looking up at the ceiling sighing to himself. A week has passed since he arrived home from the Kalos region, but since then he wasn't himself. Near the end of his Kalos Adventure, Ash had finally realized how much Serena had meant to him. However when he asked her to continue to travel with him, Serena had told him that she had a chance to train in order to try to compete against Aria again. But when she told him she would drop everything to go with him, Ash had told her to continue her dream saying that it would be wrong to take it away from her. But even though Ash was proud of giving his childhood friend some encouragement, that still didn't stop him from feeling sad and lonely. Just then the door to his room opened as his mother came in along with Pikachu.
