You are a challenger from the Johto region. You usually battle with a multiple types. All except grass, fairy, bug and basically every type that looks.. soft.

One day you decided to visit the Hoenn region. Your cousin lived there so you both decided you could stay with her for a few days before you leave again.

Today you decided to explore the Hoenn region and maybe catch some new pokemon. While walking you notice a Gardevoir following you slowly from behind. You walk towards it a bit and it gets closer as well.
