Yes, because they are only half sister, cousin etc, so not really related fully . But that is his real mum! That's what did it for me. And, I am totally fine with the others, but I was willing to put up with it because of the situation of the MC''s character not seeing any of them until now. And it is only a game and some of the other characters (like Maddie's' for example,) are fun characters to read. l. I also wished there were girl on girl action too. Like, Sandra on Maddie. Thanks for the reply.
I mentioned this before to you lol. Half-siblings are still very much related. Yeah, if, say a half-brother and half-sister have a child, there's less chance to have a child with deformities or issues, but there's still a higher chance. They still share half the DNA from one parent. Which makes them 100% related. It's not like step-siblings, where they are only related by marriage and have no blood relation.
So just imagine that your own father or your own mother had a child with another woman or man. Would you not consider them properly related to you just because the child doesn't have both the same father and mother as you?
