So basically you want Milfy City no.2 just from the mothers point of view.Honestly, I think it's important for the story that Ellie is interested in guys. Otherwise, the story between Ellie and Dylan would also be in danger, and this is probably the most important story in the game, next to the story between Dylan and Sophia.
I personally am not invested in Sofia with her kids storylines, could care less either way, as long as other content gets into the game.
