If I can have Daphne and almost-Daphne in bed at the same time, that's a win.
I'm really looking forward to the potential scenes when Eva (and Amanda) are fully consummated members of the harem. Some "twin play" or "clone play" could be fun with Daphne and Eva - so long as it's not Eva roleplaying as Daphne, as I feel that would belittle her slightly. Both roleplaying as the same
different person would work though! (And yes, I know we have had some twin time before with Daphne and Erika (but not
just Daphne and Erika, that I recall), but it's not the same because they have such different styles to set them apart).
Go play Lust Academy for a while, then come back and talk to us about poor proofreading and unnatural dialog (or dialogue, if you're on the east side of the pond...).
"Dialog" to mean conversation is apparently still a lot less common. Even in US English, I would guide towards "dialogue" for conversation, while "dialog" is used in computing, for popup/information windows etc.
Honestly, "that are" isn't actually a problem; however, the rest really is a bit bad.
When referring to people, “who” is generally used, whereas “that” is used for inanimate objects.
(I copied and pasted that one from the comments library I've compiled for use when proofreading novels. It shows how often it tends to come up...)
