A couple weeks later, a lot of things happened.
For starters, Mamoru and Usagi got married. Kunzite proposed to Minako and she heartily accepted. Same goes for the rest of the Inner Guardians and the generals. Haruka and Michiru married and adopted Hotaru as their own. Setsuna got to live with the three, as Hotaru's adopted aunt.

As for Neo-Queen Serenity, she started visiting the past much more with Endymion and their newborn daughter Small Lady. They didn't even miss Usagi's wedding.

And Usagi...she was living a happy life.

"I guess all things end with a happy ending." Usagi said.

And so she was correct. The End.
