Why would you only forgive Lyly my dear friend, share your reasons with us XD.
Because she was blackmailed. Plus, she has a difficult past, or rather the people. And in the end, they force her, although she herself is against it, but she has no choice. Of course, I have gone even further to judge. I am approximately at the 14th update in time.
Unlike Rose, who, judging by the text and what happens next, she still continues, while continuing to deceive Leto. Like Cyanna, they could have said no, but lust won. The same about Haylen, a fool is a fool. She could have refused again, but because of the fear of loneliness she went to the bastard. Although Leto was always there for Haylen, but no.
In the end, based on the passage, I can judge like this.
They are all bitches. They could have cheated, but no, and at the same time they continue to deceive Leto.
And Lily is more likely to be proud and she wants to decide everything herself, to say that they are NOT SLAVES. But judging by it, she is still a fool. But for now she is the only one I forgive, but it is clear what will happen next.
That's why I want an ending where only Leto is happy and all three girls are punished.
Example.
Haylen will go on a pilgrimage, she is forbidden to see Leto and will sit in a convent for the rest of her life.
Rose and Cyanna are banished from the island, also forbidden to see Leto. Let them do whatever they want, no matter where, just don't touch Leto.
