I like the idea that each woman gets her share, even if it's not from Daniel. But I feel that Daval's problem is that, he creates so many stories and possibilities in one that he doesn't even know what he's doing, and he just lets us see how he wastes the potential of other characters. Especially considering that Daval works on 3 different stories at the same time.
On a personal level, I think the best solution is for Daval to take a breather and then deal with all the characters he has in an unused story. That is, “Immoral Desires.” What to do if we don’t want to pair Sofia with Daniel? Easy: we pair her again with Martha’s nephew’s friend, and voila, we have a separate story that doesn’t include Daniel or Lana. The same can be done with Martha and her husband’s nephew. As stated in the first chapter, Martha’s husband lets her fuck with other people, which opens up a wider range of possibilities than with Sofia, with other types of stories, such as gang bang, interracial, etc. Then there’s Lana’s friend, Rosa, who also mentioned that she has a somewhat lazy son, so maybe seeing a new couple would be refreshing. Or Daniel’s cousin and her friend, who could also have their own separate story, venturing into the world of adult stars. Something like an Onlyfans, where someone from their school or community discovers them and blackmails them. There are a lot of interesting possibilities without using Daniel and Lana. I mean, the story is called Immoral Desires, not Daniel and Lana. If people don't want that relationship changed, that's fine, after all, ID has an even bigger cast of characters to explore. One thing that could happen is Daval pauses or ends Daniel and Lana's story, and lets other characters take center stage. That way, it doesn't hurt Daniel and Lana's story, but it explores other possibilities and no one feels like a character has been wasted.
