So about this, Khayon already made a couple great points about the relationship arc between Penny and Orion, giving a good number of
whats. I want to add 2
hows to that, one bout mechanism and one bout context. But, tho I wouldn't call it a porn VN, as far as adult VNs go you can call
Eternum at least a bit porny. If you doubt that, the last page of reviews is enough proof
Eternum's coomer-approved.
I think 1 of the consistent tropes or themes in Penny's arc is the escalation in sexual tension that I already mentioned in this post. The arc, after a near disaster breakfast, quickly builds by Penny and Orion doing some casual flirting, Orion hopes for more of course but he isn't very serious about it yet. Early on there are moments where either Penny or Orion regrets about having gone too far or doubts if it can go anywhere, and is about to break it off when the other is cheeky again and the first 1 gets carried away with that. Later that's mostly Penny having regrets. Anyway it's a pretty obvious dynamic if you look for it, it's the main way sexual tension builds between the 2 in her arc.
Another thing Orion had going for him is how he is supportive for Penny's modelling career. He's the only 1 in the Carter household that seems to spend much time helping her with it. It's easy to underestimate how important modelling is for Penny, but it's an ambition on the level of Dahlia's fitness ambition. Ambition is a core theme in the Carters' arcs overall, feels like Julius Caesar all over...
Khayon already made a point how Orion protected her from pigs in the industry, and tbh modelling really has a lot of people like that. It isn't like Orion is the only decent man in that little world, but it's not like Philippe is much of an option for her. Orion had an advantage, that he didn't know, in that she had a few precious memories that involved him too. And it does take a pretty decent chunk of time and non-sexual interaction before she decides on Orion. Yes, it sounds shorter if you, like, only count the sex scenes.
You can differ about how well the pacing or implementation of Penny's arc is. But her arc does reflect her personality. We know she's had at least 1 boyfriend before but didn't have sex yet from that Veritaserum scene, because she's been influenced by purity culture. Imo imagica understates the characterisation of Eternum's LIs overall with that summary. One simple example, I feel there's a pretty marked difference in how Penny relies on external, social validation from peers, even tho she's said she's improved since that memory scene, and how Dahlia relies on internal validation from fitness achievements... Keep an eye on that for how the plot develops.
And I don't care bout LIs' virginity either, but in the harem genre it's probably a bad decision if you don't cater to that crowd.
Tho, I'm not giving that debate a do over again, one of the worst poll dramas on this site.
So, that's the end of my TED talk.

And have a great Christmas, Eternumites.
