This ending was interesting…
I always felt that instead of “La Historia de Iván y Lucía” it should have been “La Historia de Iván y Camilo”, as these chapters were about the friends forgiving each other.
After a fake attempt to tell us that Camilo is daying, the next take is him returning the rosary to Ivan on his wedding with Lucía (they should end up together instead)
There were a lot of outcomes for the antagonists. Juan Jaime, despite being forgiven by Ivan, ends up all alone and not wanted by anyone in their lives. Saul takes up his life after realizing he's a useless human being in both physical and moral. And Marypaz dies by trying to prove she is changed and good but sacrificing for her mother, everyone just pity her at the end.
Another interesting end cycle returning to Camilo was that the whole conflict started by Ivan thinking he killed someone in order to protect him (a lie as it was Antolin). Now that Saul and El Gordo kidnap Alex, when him and Ivan go try to save him, Camilo does eventually kill someone to protect his friend.
Now in the main ending there was an Indigenous healer who takes care of both wounded men, personally I’m not a fan of Televisa representations of racial minorities (especially in a plot that didn't need that) and with some characters asking if they are not dangerous
One really big issue in these final chapters was the product placement. Characters break into how good a cooking oil is, a canned vegetable brand or even worse, our main couple planning their wedding in a famous department store
Finally… I hate white groom suits!

Unless it's a charro/mariachi suit stick to black/blue/gray. The black one Ivan used on his wedding with Marypaz was a lot better.
The last scene of Ivan and Lucía is just beautiful the production was on point in here, levels over La que no podía Amar or Amor Bravío.
