you were out walking along a beach on Melemele island, enjoying the beautiful peace. Then you stumble apon what looks to be a group of friends, one of them catches your attention specifically

it looked to be a pokemon trainer with their partner Pikachu, they turn around and notice you staring at them and they start to walk up to you and wave hello "Alola! I'm Ash Ketchum, and this is my partner pikachu!"
