I know some of them already had bad endings

Carla Lu and Marina for me. I know they used to be friends in season 1 but I wish they had more scenes together like Polo, Guzman & Ander. Oh and same for Patrick-Isadora-Ivan for some reason lol. Isa and Ivan are besties now but they barely spoke in the fifth season. Also her and Patrick would have the opportunity to become a chaotic duo if they had more screen time. How about you?

I wrote about this before btw

• Carla: It's bittersweet. She can be dating some British guy who was raised in a rich family, she's still not the extroverted kind like Lu or Valerio but nor the mysterious and secretive type anymore. She most likely found out about Samuel's death and was very heartbroken at first but pretty much moved on eventually. I also think she might have reverted back to her season 1 self
• Nadia: We'll know next season. I really hope she ends up with some kind and selfless guy. I know an endgame relationship isn't needed for a happy ending since she got accepted in a very good university and pursuing her education was her goal, it's just that she deserved better than Guzman and Malick.
• Caye: Maybe endgame with Felipe, a guy who truly cares for her. Is planning to be a fashion designer. She had a proper ending on season 5
• Ander: Maybe still in contact with Guzman and is dating another guy now. However I think he got a happy ending too, he escaped his father's ideas of what his career shall be, his guilt & fear towards his illness. Has explored his sexuality and knows himself better. Has now a chance to live an experience that should help him reconnect with his true self, by travelling with his best friend. Also mostly recovered from cancer and could move over the past
• Lucrecia: Dealing with her killing Polo and trying to recover from being disowned too, isn't that social compared to before but has Nadia and some more friends in university.
• Valerio: Still in contact with Lu and working for the Calruega wineries. At least he ends up being a major collaborator in an important business ran by a close friend of his sister. It's not shady shit, and he has a chance to make a career without going back to the things that he ended up regretting.
• Guzman: There's a quite high chance he isn't doing so well now. He may be having guilt from Samu's death and wish he wasn't so mean, and also about killing Armando. Might not move on from Nadia and it's rather likely he reverted to his season 2 self when he was still grieving and possibly using drugs again. Luckily Ander may help him if that's the case
• Christian: Dating some hot chick or guy in Switzerland. Still a cripple
• The Blanco twins: I have a feeling Mencia has chronic depression due to what happened before as she thinks she hit Ivan & most likely won't find out the truth. If she does she'll feel betrayed as heck. Remember in the short story where Patrick has visions of her overdosing? That might happen to her. Ari may either change or is still a cheater like before and help her siblings. Patrick misses Ivan & is probably miserable as hell until he hears Ivan's current condition but still dislikes Benjamin as much as Mencia does
• Phillipe: I hate him as much as y'all do, but he may feel bad for his actions and wish he was there for Isadora. Studying on some VIP or prestigious college in Paris. Probably having a somewhat bad social life than before due to the controversies
• Rebe: ??? The writers didn't even give her a proper ending. I can guess she's dating someone helping her recover from Samuel's death who she later catches feelings for in university

I heard many cast members unfollowed him due to some controversies which was long ago, what did he do?
