Omg yes. I so want more soft content, espevially with slaves, but also with the newer owner system. I'm sadomasochistic myself, but what's the point if it's not balanced with softness? It just gets boring and feels bad.
And yeah totally needs more male characters. Even the male characters in the side stories feel like they're just there to be secondary to the women. Alex is pretty much the only male character that's important. Maybe that will change once the betraying Tavi option is expanded, allowing you to get closer to the Captain.
