I think the biggest difference between western and eastern media is that the west is preoccupied with pinups and spectacle while the east is all about drama.
There's a visual novel jam going on in March. The 5th year of NaNoRenO on itch.io
. The turn out is usually fair, much higher than BaraJam. But I've notice a characteristic of a majority of entries feature external -non social- conflicts. That is they lack drama or any kind of emotional relativity.
A general impression would be a story about a character in a desolate environment and they're really stoic about their circumstances. Compared to a character on a plane full of hysterical people.
I see this in porn as well. Without mentioning any name, again, these are broad paint strokes. It's like the sex (in western media) is consensual, instinctual, maybe even accidental. Fundamental. Often ending in a sex positive one-night stand and a promise of a call back. The sex was good but there's nothing between the characters.
Which is very different from rape, fucking your best friend's dad, taboo incest, accidentally sending nudes to the wrong person resulting in black mail. Getting caught in public. You know. Drama.
