A childhood friends AU where the powers of the miraculous are in-born and are very rare. Adrien met Marinette once when they were still very young. They don't remember much of it, but Adrien always remembered her as his first love. When he steps up to be a hero of Paris alongside Ladybug, Chat immediately falls for her, because without a doubt in his mind, she's his first love.

Adrien takes a walk in the rain with Marinette, and something finally clicks.

What happens when Adrien says the wrong name at his wedding rehearsal? Would his fiancee ever forgive him?
