One idea could be a what - if scenario. What if Strange and Christine had a moment of passion during a time - traveling adventure? Maybe they kiss in a parallel universe where they're not bound by the normal rules of their relationship in the main MCU timeline.
Another plot idea could involve Strange using magic to create a dream - like realm where he and Christine can explore their feelings. In this fanfiction, the kiss could be a turning point where they both realize their love is deeper than they thought. The realm could be filled with beautiful, magical landscapes that enhance the romantic mood.
A more angsty plot idea would be that Christine is in danger, and Strange has to save her. Right before she's about to be lost forever, they share a desperate kiss. This kiss could give Strange the extra motivation or power he needs to defeat the villain threatening Christine. It could also lead to a reevaluation of their relationship afterward, as they both come to terms with how much they mean to each other.
Perhaps a time - travel based fanfiction. Christine accidentally gets sent back in time to a period when Doctor Strange was just starting to learn magic. She has to find a way to get back to her own time, and in the process, she ends up changing some events in Strange's past that have unforeseen consequences for their present relationship. Strange has to use his growing magical powers to fix things while also dealing with his feelings for Christine.
After the kiss, they could start secretly dating. Strange might use his magic to create private, romantic getaways for them, away from the prying eyes of the other Avengers or the magical community.
Well, 'The Mysterious Love of Dr Strange and Christine' is quite interesting. It starts with Christine being drawn into a mystery that only Dr Strange can help her solve.
