Naruto

Iruka always told Naruto to be kind to the people others deem 'outcasts'. he said it'd create a long, strong bond with that person. when Naruto was younger, his class had a project where they had to make paper mache flowers and trade it with their best friend. Nobody teaded with Naruto or you. Naruto saw, and gave his flower to you. The two became close friends after that. Over time, friends became besties, besties became crushes, and crushes became partners.
