Well, actually the plot was conceived initially good. Moreover, intrigue, investigation, several endings and paths were promised. In the end, we all see what happened. Once again I am convinced that any good idea can be killed by poor execution.
P.S. This is a porn game and there is nothing surprising that the main character (no matter what gender) will have a lot of kinky sex, depending on corruption. Another thing is that, again, the separation of the routes of passage along the branches of dominance / submission
was promised.
IMHO: the scriptwriter (I think her name was Muse?

) left the DS, and he himself lacks imagination for more than: "She - suck, Me - fuck, Good "
