I spent a long time fleshing out a post-apocalyptic (due to worsening environment, not war) and got some ideas for it over time. One of them is a horror (body, psychological) BL that punishes certain kinds of men into becoming more "pleasant." They are ranked after being processed to start their new life as a redeemed(lol) man. As an example, after processing, if their ikemen value is low, but their body is high with great athleticism, they may be sent into combat sports. The ones with true talent in any area have the highest rank.
It's almost the opposite of
>>12, as there's no reprogramming men to become gay; more like they might be made to do gay things to entertain. The ones who are more enthusiastic about it gain more freedom; but the ones who don't, if they don't maintain enough points within a time period, are offered as gifts to the highest ranking men, or auctioned off.
Many of them hope to be released by the woman in their lives that they've wronged; but they are there because the harmed they've caused was significant to the woman's life and well being (as opposed to a mild insult that would have the same meaning if a man were on the other end; even a sexist remark wouldn't cause this, but it is a red flag. A woman can record the frequency and turn them in.). At the very least, they hope a woman buys them. The ones actually attracted to men don't mind it too much and don't spend much time at the bottom.
The ML is right at the very top. No one knows what's up with him. But he's sweet, pure-looking (like Xie Lian kind of pure, idk), and admired. He visits all of the men before their processing and gives them hope before leaving.
I haven't decided on who will end up with the ML. I thought it might be fun to figure that out while working on each character's situation. I'm planning for 8, but just fleshing out four for the time being. A situation that suddenly doesn't work for one guy ends up jumping into another one's.
Post-apoc setting is necessary for this. There is a big societal reset in progress.
You can probably see elements of things like Ai no Kusabi in there, but I've always preferred BL/yaoi with more sci-fi and fantasy elements.
Per my outline, this might veer right into yaoi hentai and some notes edge on guro. I just let the ideas flow. Curious where it'll end.
