After the kiss, they might be shy and awkward at first. They could avoid each other for a while, not sure how to handle their new - found closeness. But then, they would start to miss each other's company and slowly come back together. They would start to communicate more openly about their feelings and the relationship would gradually grow stronger.
One possible plot could be that they are on a mission together in a dangerous situation. As they face numerous challenges and rely on each other for survival, their bond deepens. In a moment of intense relief after narrowly escaping death, they share a spontaneous kiss. It could be a story about two characters from different backgrounds coming together through shared experiences.
After the kiss, they might be a bit shy at first. They could start to be more open with their feelings, like Drew bringing May small gifts related to Pokemon, such as rare berries for her Pokemon. May would probably start to blush more around Drew and be more eager to team up with him in battles or contests.
After the kiss, they could enter a sort of uneasy truce. Batman might be more hesitant to fight Poison Ivy directly as he's now aware of a different side of her. Poison Ivy, on the other hand, could start leaving clues for Batman instead of causing outright chaos, like she might target only the really bad polluters in Gotham and leave a calling card for Batman to find. This way, they start to work in a strange, unspoken partnership.
Their relationship might also face some challenges. Maybe the other demigods don't approve of their relationship for some reason, like it goes against some unspoken rule in the demigod community. So they have to fight not only for their love but also for the acceptance of their friends and peers. However, this could also make their bond stronger as they face these difficulties together.
After the kiss, their relationship could become more complex. Lydia might find herself more drawn to Beetlejuice's wild side, and they could start going on more adventures together. For instance, exploring other parts of the afterlife or using Beetlejuice's powers to have fun in the living world.
Before the kiss, their relationship might develop gradually. They could start with simple conversations, sharing their thoughts about the ninja world. As they spend more time together, they might begin to trust each other more. Maybe Naruto shows Fuuka some of his favorite spots in Konoha, like the ramen shop, and they start to understand each other on a deeper level.
They could start a tumultuous relationship. After the kiss, the Enchantress might try to further manipulate Thor into doing her bidding. But Thor, being a hero, would resist her advances and try to redeem her from her evil ways. This would create a push - and - pull dynamic between them.
After the kiss, they might start going on secret dates. Since Monster High can be a bit judgmental at times, they could meet in the old abandoned part of the school. They would hold hands and talk about their dreams and fears, getting to know each other on a deeper level. Their relationship would grow slowly but surely as they discover more things they have in common, like their love for fashion (Draculaura's gothic style and Clawdeen's fierce looks) and their loyalty to their friends.
After the kiss, they might start to communicate more. Naruto could be curious about Rogue's world and powers, and Rogue might be interested in Naruto's ninja skills. Their relationship could develop as they exchange knowledge. For example, Naruto could teach Rogue how to use chakra in a different way, and Rogue could show Naruto some stealth techniques from her world.
They could start a secret relationship at first. Since they might have responsibilities or there could be some sort of social or group dynamic that makes it difficult for them to be open about their feelings right away.
