You. Me. Forever. Oui.

I will always love hearing people’s love stories. How they met, how they fell in love, how the proposal happened, and all the little moments that brought them to their big day.

And this cake was exactly that. A love story coming full circle. The beautiful closing of one chapter and the beginning of another.

From a proposal in Paris to saying I do, every detail of this cake told a story.

Because at the end of the day, it will always be You, Me, Forever. Oui.
