Searching for Ash/Alain story
I can't find a story I read about Ash/Alain but what I remember is that Ash is in Alola and has Nebby, who teleports Ash to Ten Carat Hill in the middle of class and he lands on top of Alain who was in Alola during research of some kind. They aren't together during the beginning of the story but Ash has a crush on Alain for sure.
