Eh.
The thing is none of the writers within the team know how to write romance very well, likely because they themselves just haven't experienced it in a healthy manner or at all.
Romance in porn games just equals to pressing the talk button 5-6 times then smashing or doing a quest then smashing.
Personally I don't really find a meaningful distinction between friends and lovers if all I need to do to ungrey the fuck button is to press talk and skim over 2-3 different backstory drops I couldn't give less of a shit about. I wouldn't really call that attaching feelings to the character because people in real life aren't willing to actually go on 2 hour tangents of oversharing with you. Now the second measure porn game devs take with that is to split the "talking" phase into forced time limits, where you have to visit them every once in a while to progress. But again, all of this feels arbitrary as shit rather than an actual person to person interaction.
There's no real way to win when it comes to writing proper romance in a porn game, or at least I haven't really seen any.
I personally think romance in porn games can only really convincingly work by not trying to be like a "pure romance" at all, e.q. love born out of something other than traditional courting. Like Arona. I can somewhat buy Arona's romance because she is a batshit insane woman from a batshit warrior clan where defeating the shit out of her dozens of times might actually have gotten through her in a way. And you still have to take a while with her afterwards until she opens up. I can't buy any normal romances ever though, it will always devolve to shitty talk scenes.
Arona have fans, despite being a generic dommy futa (what a novel concept), because her character path/presentation to the player is consistent and quote unquote 'faithful to the world'. Consider next takes
Shes and orc -> ah yes 'orcs', more known in porn games as 'oaks', dumb brutes that understand only a language of strength and violence
First several encounters with her is just a fights -> ah yes, that because shes an orc which mean she 'that understand only a language of strength and violence'
After beat her/player get beaten X time in a row she comes to player and asks for a help in putting her brother down -> again, \'language of violence', but 'get beaten' path breaks her character. If player was beaten into submission why does she need some, any, help from a weakling in a battle? Shes dumb, yes, but not in a fighting field. I mean....Okay, fine, whatever, lets assume she was desperate and just move on, I dont want to delve here into analysis like 'what tobs meant to say when he break smut scene to describe color and material of drapes in a room on the other side of a street?'
help or
help her -> outcome doesnt matter, unless player picked 'get lost' option in
help path, its now possible to talk with her.
On talk about 'why do u have pp' she says something like 'cause its awesome and its the only way to dominate weak (or something like that, dont remember exact words)'
Questioning her 'how do u get pp' she answers 'just asked my homie shaman for one, she asked gods for it and gods said 'get gangraped, slut, and make sure everything end up inside of you' so I did and now I have it'.
The more player interacts with her the more she solidify her initial appearance/impression of a spherical orc in a spherical vacuum, reference copy of which could be found in
International Bureau of Weights and Measures located in Saint-Cloud near Paris, France.
That what I meant by 'feelings'. In other words '(abstract) value/cost attached to character, which based on all interactions with said character and how they connects into a single
image'.
