In this fanfiction wedding, not only their friends but also some of the heroes they've worked with in the past could be guests. Rena Rouge and Carapace would be there, having played important roles in many battles. Maybe even some of the one - time heroes like Pegasus or Viperion could show up.

There might be a secret mission that Ladybug and Chat Noir have to undertake during the ball, and they have to navigate through the crowd of masked people to complete it.

Another possibility could be a new character introduced specifically for the fanfiction. Maybe a powerful and charming hero from another city comes to Paris to help Ladybug and Chat Noir.

Also, it can explore the emotional and psychological aspects of the characters more deeply as they deal with this new type of character. It gives fans a chance to see their favorite characters in a whole new light and in situations that the official show may not cover.
