Accidentally Smitten: A Childhood Engagement Story

(Crossposted From Ao3)
It was embarrassing. Really embarrassing. Hell, it was a miracle neither of the three parents brought it up since they were children and had helped choose a "ring" and plan out the wedding with them. This, of course, was never forgotten by either, even when Katsuki pushed Izuku away or when they began their odd deal.

Unfortunately, in the aftermath of their class, and Monoma, learning about their monetary deals and their parents excited for their rebuilt friendship, the teasing of their childhood engagement came back in full force...with their parents sending them back to the dorms after visits with various weddings items to choose from like invitation designs, outfits, etc.
It was very embarrassing, especially when their old kindergarten wedding photos were sent to the dorm with them and discovered.
