Marissa and Carder met a number of years before they had their first date, actually. They had mutual friends and even ended up being roommates, never thinking much of it. Marissa moved out of their house and down to Florida for a few years so she could discover herself, causing them to lose touch. When she came back home from her adventures and got settled back in Georgia, Carder reached out to her again, and there was no turning back from there.
Carder has never been good at keeping secrets, so naturally Marissa knew exactly what was coming. Upon arriving for a vacation in Florida, they unpacked at the hotel and immediately went for a walk along the ocean. Carder thought this would be "as good of a time as any" to ask Marissa for forever. He slowed down and let her get in front of him, then tapped her on the shoulder, and was down on one knee as she turned around. He did not account for the fact that there were waves crashing where they both were standing. Right as he asked the big question, a waved pulled all the sand out from under him, he lost his balance and toppled over into the water, landing on his face. Seeing this made Marissa fall in love with him all over again, and she said yes.
