It's actually other people that say that.
Nana won't be that late in the game because all her content comes after the first sex scene
V0.10 is Jamila heavy
Do you mean Mila? I won't be changing her, I like her look.
MC won't be telling the rest of the family about the baby until he introduces them to Tanya and he won't be introducing her to anyone until she settles in.
There's also what you said about the technical reasons. She already got half an update dedicated to her plus a chunk of the next one. I can't focus too much on any one person or you won't see anyone else for a while.
Unless I'm forgetting, I think you got your days mixed up, Elaine said that after the family dinner a few updates ago. I don't see why you would find it surprising that they're leaving already, they said it was a one week visit and it's been over a week.
Amy won't be finding out off screen, she'll be introduced to Tanya.
I probably could have worded it better but you're reading way too much into that one line. He was referring to people like Karen and Lina who are just random chicks he might have slept with. There's no point having a long discussion about his dating philosophy with them because they're not dating.
MC didn't think to tell Cat because there wasn't a romantic relationship between them at that point, they hadn't even kissed as adults yet. Plus she already kind of knew that MC dated multiple women, he was always like that. That was more of a reaction to it happening right in front of her.
Similar with Priya, not much of a relationship between them. When things get more serious, they'll have that chat.
Everyone that needs to know (More than a sexual relationship) will have the talk with MC at one point or another but there's a time and a place. In my eyes, as long as he has that conversation with them before they have sex, he's not being manipulative. A little selfish maybe, but not a manipulative bastard.
Nana knows if you're on the Tanya route, otherwise he'll have that talk with her at another time. But she also kind of knows, MC kind of explained it at breakfast with Nana and Amy, she also lives with him.
Not sure what you expect MC to do about the last part, Amy fell asleep.
Thanks for the feedback and glad you're enjoying it.
You would probably enjoy it a lot more if you took it for what it is though. A nonsense harem fantasy with no drama and no realism.
