A lot of Boys Love story are written by straight women fetishising same sex couple between man. Therefore, when they write the 'Bottom' or 'Uke', they will represent 'traditionally' (or toxic ideals) feminine features in either personality or looks.
Keep in mind that straight people are still influenced by the traditional culture of what men and women should be like how or how they should behave. Women are valued by men when they're an innocent virgin who are pure.
When straight women write the 'Uke', they will make it a self-insert for their target audience (women that fetishise male couple) so these women can imagine themselves as the pretty 'Uke' who embodies the "innocent", "pure" stereotype you found.
But like I said, they fetishise male couple so that means the audience want to see sex happens. But, sex must be done by the consent between two lover so how can it happen when the 'Uke' is supposed to play the role of an 'innocent beauty'? The 'Uke' MUST NOT initiate sex or show even the slightest interest. That would destroy the women's fantasy because they can't insert themselves in an 'Uke' who doesn't represent the toxic ideals of feminine quality.
So how do you solve this? Sexual harassment, rape and drunk sex.
You can find the similarities when you compare Boys Love fiction written by straight women (that fetishise male couple) versus straight-romance fiction written by straight women.
You will find A LOT of similarities between the 'Uke' and 'Female Lead'. You'll understand better what I meant.
Wow acc phenomenally written! Great job on the analysis
Why is every beautiful artistic and uncensored story I stumble upon just more and more rape, violence, and/or manipulation??
Just... why?
What's the reason for all this consistent sexual violence??
