Darling in the Franxx Season 2

My petition is about the anime "Darling in the Franxx" which unfortunately only has 1 season. I find it very disappointing that this wonderful anime doesn't have a sequel, especially since everyone didn't like the ending. I would like to get the A-1 Pictures animation studio to do a sequel through signatures.
This anime was just amazing. I was so touched by this anime. Just like so many others, I didn't like the end. Everyone marries and doesn't have children, only the 2 main characters. You sacrifice yourself for humanity and get nothing. I would like very much if they bring out a second season
where they both fly home and have children too. Especially since he now also has blue horns. I really want to see a second season of it so that you can find out how the relationship between the two continues and how they are together. The anime Darling in the Franxx definitely needs a second season.
I will fight for it and I hope you will help me with it. I think it's a shame that such beautiful and good animes don't get a sequel, but some other weird and stupid animes do. With this petition I am trying to get the A-1 Pictures animation studio to release a second season.
But Darling in the Franxx isn't the only anime that affects that.
