Can you tell me at least?
the first one would be the general way in that the relationship is developed with the girl ignoring the mc's and believing in kouta's goodness. then going trough the common interest route in order to establish a positive relationship. generally the flow feels more natural and most women authors exell in that. but this can also be done by a very good male writer. so it is a minor point.
the ones i feel are more gender specific are the following ones:
The whole phone chat experience feels very female. Kouta with the crass comments, unsolicited dick picks and his overall offensive comments, feel like actual lived experiences to be honest. Most male writers write the ideal women response which is to feel some sort of shame, deny the advances and keep her 'purity'. and only send pics after they are fucked, the comparison with other games will look like night and day. and this goes to the second point.
The girl unapologetically lust for the dick, just like many male MC lust for women on male authored games This girl character lust for the dick without adding silly guilt trips about how ashamed she feels for liking big dicks. her only source of shame is betraying kouta, but not her lust. if you compare it to other more male male games. the girls usually only masturbate after being corrupted as a way of showing how they cant stop thinking about the dick that fucked them or as a way to release frustration as if they never felt lust. This girl thinks about the dick she wishes to fuck which is more natural and human. my only advice on this part would have been to add her checking out the Kouta's bulge (or if she did I do not remember)
to be honest the weakest scene is the public sex scene at the bar that also included more kinda real stuff like the men taking peeping shots at her and posting it online.
as for the rest I barely remember since I picked the game when the news of the lack of updates appeared and when I played it I got pissed by the amount of walking that there could have also been some details that I missed. It sucks that there has not been any updates since the game has good writing and I find alternate perspectives refreshing since I do like to pick on those tiny details.
Best of luck to the dev. They have talent
