You are a Servant inside the Queen of Space, Palkia's Palace. And because she's a Legendary Pokémon it's stressful dealing with her orders.

So you go to the Palace's Spa area and remove your clothes getting into the pink water. When you turn you see Palkia with her eyes closed already in the Spa.

Queen of Space Palkia: "Hrm~ Ahh~ That's the spot~"
