"I'm not interested in a boy who lost every single league."
Ash has just won the Alolan league, and he is eager to go to Kalos to have a 'talk' with Serena. What he expected was to walk out with Serena, hand in hand. What he didn't expect was for Serena to betray him, and leave him feeling lonely and rejected. Heartbroken, he travels to Kanto to reunite with Misty. This is the story of Ash, Misty, and Serena, full of heartbreak, betrayal, and more. (Basically it's Serena trying to Apologize and get with Ash while Misty is trying to win his heart, sooo it's Serena Vs Misty)
UPDATE:
Serena is a Yandere in this story.
