There's also 'Alex and Maggie: A New Chapter'. It's a fanfic that focuses on their future. It explores what could happen after the events in the show, such as how they might start a family or deal with new threats in the city while maintaining their relationship strong. It has some really heart - warming moments that any fan of the couple would enjoy.
I really like 'The Bond Between Alex and Maggie'. This fanfic delves deep into their individual backstories and how those experiences shape their relationship. It shows how their different personalities complement each other, like Alex's seriousness and Maggie's more laid - back nature coming together in a really interesting way.
