Who could be the main characters in a 'rust love story'?

Since we don't know the details of the story, it could be two ordinary people. Maybe a man and a woman who live in a small town with an old, rusty factory nearby. They could be neighbors or coworkers.

The main characters are Isaac English, a young man who gets involved in a complex web of events. Harris D'Angelo is also a key figure. There are other characters as well, but these two are central to the main plot, as their actions and decisions drive much of the story forward.

Perhaps it's a story where a young woman discovers an old, rusty locket. Inside is a picture of a man from long ago. As she tries to find out more about the locket and the man, she meets a historian. They work together and end up falling in love during their search for the locket's history.

It might involve a couple who meet in a rusty old town and fall in love against the backdrop of decaying buildings and forgotten memories.

I'm not entirely sure, but Bisco is likely one of the main characters since the title mentions 'rust eater bisco'. There may be other characters that interact with Bisco, like friends or foes, but without reading the novel, it's hard to say exactly who they are.

It could be a group of coworkers. They work in a competitive environment, and there are rivalries, alliances, and betrayals among them. Their stories are full of drama and emotion, just like in a love story, but there is no romantic love involved.

There could be a young, adventurous dolphin called Dash and an older, wiser dolphin known as Pearl. Dash's energy and Pearl's experience create an interesting dynamic as they fall in love. They teach each other things about life in the ocean and their relationship grows.

It could be a young adventurer and an old wise hermit. The adventurer stumbles upon the hermit's dwelling during one of his expeditions. Despite the age gap and different outlooks on life, they form a deep bond that neither of them expected, which is an uncharted kind of love.

The main characters could be two goldfish. One is a bright orange goldfish and the other is a shiny white one. They meet near the little castle in the aquarium and start to develop feelings for each other.

It could be two cyborgs. One cyborg might be an older model, more mechanical in nature, and the other could be a new, more advanced model with more human - like features. They might fall in love as they learn from each other and discover new things about their own existence.
