One reason could be that Percy has shown great courage and strength, which Reyna respects. She might see in him the potential to be a great ally or even a leader. So, she becomes protective to ensure his safety and to keep him on their side.
In a fanfiction, their friendship could start with a simple act of kindness. Percy could save Reyna from a minor accident. Reyna, being grateful, starts to see Percy in a different light. They begin to have small conversations, getting to know each other's likes and dislikes. Over time, they realize they have more in common than they thought. They support each other in their personal goals, like Percy helping Reyna with a project for the Roman camp and Reyna helping Percy with his relationships at Camp Half - Blood. This mutual support cements their friendship.
Another scenario might be when Percy is in a dangerous situation like facing a powerful monster. Reyna would not hesitate to put herself in harm's way to protect him. She might shield him with her own body or use her strategic mind to come up with a plan to keep Percy safe.
Jason is another good choice. He has a history with both Percy and Reyna. His leadership skills and his connection to the Roman side of the demigod world could bring in new plotlines. For example, he could help Percy and Reyna understand some of the more complex Roman demigod politics that they need to navigate.
Their relationship could develop slowly. At first, they might just be acquaintances who respect each other's abilities. Then, as they spend more time together, they start to have small conversations that gradually become deeper. Eventually, they realize they have feelings for each other.
