Id rather make the relationship brother sister than dad and daughter if its that in the incest pach ( I played the regular + you should make it so you can edit the relationships) mc looks too young to be a father. It makes more sense brother/sister cause they are all living together trying to work things out paycheck to paycheck, maybe you can say they moved to a diff city and they are trying to make things work idk. Good models tho, very nice

Not that I disagree entirely.... I wouldn't call myself an incest fan but I don't avoid VNs with it (because that'd eliminate almost all of them). Though if there's incest involved then I'm firmly in the "siscest is bestcest" camp too

And Daddy/daughter cest is always kind of creepy to me. But with that said, it seems that the father/daughter relationship is necessary to the story given Emily's mother and grandparents being involved. So I'm fine with it because I'd rather the character relationships make sense in context to the story. I just have to remind myself that it's just perfectly normal family bonding in world of VNs
The characters do look young but assuming they're eating right, 30somethings
can look like they do. So their ages aren't all that implausible to me. It just means MC knocked up a girl when he was 16. Totally happens irl. As far as the girls, they seem fine to me. Emily is definitely tall enough and filled out enough to be 18, Melody looks like and acts like she's college aged, and I've known 39 & 40 year old women that looked like they could be 29 so Lucia looks fine to me too.
So the age thing doesn't bother me in the slightest especially when they start taking their clothes off

Besides, I'd much rather characters looking a little younger for their age rather than older.
