Well, in this kind of fanfiction, the relationship between Jack Frost and the original character (OC) can be really diverse. It could be a friendship where they start off as strangers and gradually become close pals, perhaps sharing their unique powers and experiences. For example, the OC might have a special power related to nature, and they team up with Jack Frost to protect the world from some dark force.
Another plotline could be the OC being in danger, and Jack Frost having to rescue them. This could be because the OC has a special power that some evil force wants to steal or because the OC has accidentally stumbled into a dangerous situation while exploring the magical world. Jack Frost then uses his ice powers and his wits to save the OC and keep them safe.
One possible plot could be that Jack Frost is corrupted by a dark force. He starts to spread winter not as a fun, playful season but as a harsh, unforgiving one. He might turn against the other Guardians, believing they are holding him back from his true power.
Pitch Black would be a likely main antagonist. He could manipulate Jack Frost into turning dark, as he has a history of preying on the insecurities of the Guardians.
