I had this issue with the other kinda famous erotic RPGs TiTS and COC1 and 2.
Sometimes your party members bang each other or other people around. Now I know that the universal language in these games, but I feel a little off about it. I'm not into making a harem. But would like to marry or date long term a character. I like the idea of finding one character in these games and only having sex with them. While trying to heal up at an inn in ToA, once I had the full party (just got Urka), I was blown away with how my other party members just slink off to fuck each other. SMH I'd like to suggest the marriage option.
If marriage or long term dating isn't a possible, then fine I live. But IDK, I thought once I rose my charisma up and talked more with Trudy and Kylira that we'd go stead they way the Mermaid and Dullahan foreshadowed. Is that just not in the cards at all?
EDIT:
Got deeper into the game and the recent update.
Okay, I stand corrected. There have been more tender compassionate love scenes added or I just now found them. At least with Kylira. Still marriage or dating would be nice.
