One possible plot could be that Jack Frost, being the spirit of winter himself, is intrigued by Elsa's ice powers. They could start by having a friendly competition to see who can create the most magnificent ice sculptures. Their powers combined might accidentally create a new, magical ice realm that they then have to explore and protect together from an approaching threat, like a dark sorcerer who wants to steal their ice magic.
One possible plot could be that Elsa and Jack Frost meet by chance in a magical realm that bridges their two worlds. They fall in love quickly. Then Elsa discovers she is pregnant.

Eventually, they become friends and Jack realizes his mistake and returns Elsa to Arendelle.
One idea could be that Elsa and Jack Frost discover they both have the power to control elements in a unique way. They could team up to save a magical world that is being threatened by a dark force that can nullify their powers. Another plot could be that they meet and initially clash because of their different approaches to using their powers, but then gradually learn from each other and fall in love.
Their interaction could be really magical. Elsa, with her ice powers, and Jack Frost, who is also associated with ice and winter, might start by being cautious around each other. Maybe they'd compare their powers, like how Elsa can create elaborate ice structures while Jack can make it snow and freeze things with a touch. They could also learn from each other. Elsa might teach Jack about controlling her kind of ice, which is more about building and creating, while Jack could show Elsa how to have more fun with ice, like skating on frozen ponds he creates just for that. It could be a really interesting exchange of skills and personalities.
One possible plot could be that a magical anomaly causes the worlds of 'Frozen' and 'Rise of the Guardians' to merge. Elsa and Jack Frost meet and are initially suspicious of each other.

The plot could involve Jack Frost having heard tales of a powerful ice queen in a far - off land. He travels to find her.

However, as Jack shows her his powers and his love for winter fun, Elsa warms up to him (pun intended). Their kiss could be a turning point in their relationship where they decide to explore the world together, using their powers to bring winter joy to different places. They might also face some challenges from the people who fear their powers, but their love for each other and winter gives them the strength to overcome these difficulties.

They might face some bullies in school who are jealous of their growing relationship. And in the end, they learn to accept each other and themselves, with Elsa becoming more confident and Jack becoming more responsible.
