Lily has virtually all of Quinn's flaws with even less sentimentality, how is this not a toxic relationship?
Sage, even past the Chad issue, with her outbursts, her resistance to a “normal” relationship remains a less than ideal relationship.
i rules Jill out because it is the relationship least on the edge, but there is no shortage of gray areas; we shall see how the relationship with the Royces goes and what problems they bring.
At the end of the current history Lily recognized all her flaws openly , she is loyal to the Pink rose girls and yes, there is no romantics feelings but she is pretty clear with this in her "let's roll" opening. Quinn in the last chapters appears to start to have feelings, indeed, for Tremolo (in the others path), but even then she lied to him to be her bodyguard meanwhile she is buying drugs, for example
And Sage, well her relationship isn't perfect, but it's evolving since the beginning and in the current moment of the history, the drama is waning (we are talking about a AVN, it has to be some drama and the ideal relationship will exist only at the end of game, if you are lucky)
