Walkthrough: After meeting with Professor Kukui in Malie Garden, you will next help and escort Lillie to the Malie City Library. After meeting Acerola and learning a bit about the Legendary Pokemon of The Alola Region while at the Library, you will then head out of Malie City to Route 10 on your way to your next Island Trial. Even though the Alola Region doesn't contain Pokemon Gyms, there is actually an unofficial one found in Malie City that imitates the one found in Vermillion City back in the Kanto Region.
