Another possibility is that they are on a mission as Ladybug and Chat Noir. They get separated from the villain and find themselves in a secluded alley. In that moment of relief and closeness, they give in to their feelings and kiss. This kiss would be a bit more rushed and urgent compared to the one at the dance, but still full of love.
One more to consider is 'Kiss in the Moonlight'. This fanfic sets the kiss in a very romantic and dreamy setting, perhaps under the light of the moon during a special event in Paris. It explores how this kiss could be a turning point in their relationship and how it might impact their future interactions in the Miraculous world.
Well, it could be a really sweet and tender moment. Maybe it happens after a big battle where they've finally realized their true feelings for each other. Marinette, being her shy self at first, but then Adrien takes the lead and they share a gentle kiss that makes the whole world seem to stop for a moment.
I really like 'Adrien's Discovery'. In this fanfiction, Adrien starts to notice Marinette in a new light. He begins to see all the little things she does for him and how selfless she is. It has some really heart - warming moments, like when Adrien defends Marinette from Chloe's mean remarks. It's a great read if you want to see more of Adrien realizing his feelings for Marinette.
