Fanon
The shipping began in one scene of The Avengers when Natasha asked Loki if he's mad when he was arrested. Fans believed if Natasha and Loki are canon, Loki would say to Natasha something that would make up for the Avengers then hook up with her.

Loki and Natasha's personalities clashed but fans think it mix well. Other than that, they believed that the ship work as both are reformed villains. Fans feel like if they were to get along, Natasha would accept Loki for who he is, having to hear about his hard background. She would be more understanding to him and be someone who would always have his back. It would start off as a friendship and grow into something even bigger with time.

Many fanworks involve Loki being punished after the events of The Avengers by being changed into a human, sometimes Natasha was his handler or teacher, or sometimes they just meet again. Other than that, some also involving Natasha being included in canon events where she was not present, like Thor: The Dark World or Thor: Ragnarok.
