I don't have enough information to say who they are exactly. They could be ordinary people with an extraordinary story, or they could be well - known in a specific community or area.
One possible scenario in such a fanfiction could be that Adam has had a really tough day at the studio, facing a lot of criticism. Tommy then steps in to comfort him. Maybe Tommy makes Adam his favorite meal and they just sit and talk about their dreams and how they won't let the negative voices get to them.
It's a true story. The show takes inspiration from the actual experiences of Pam and Tommy, but as with many adaptations, there could be some artistic liberties taken to make it more engaging for the audience.
It's a mix of real events and some dramatization. While based on real people and incidents, there are likely elements that have been embellished for entertainment purposes.
