I don't know if you will like it but King's Maker is a really really reaaaaalllyyy good one!
I agree, I feel like BL is over sexualised a lot of the time. Sasaki to miyano is very similar to shoujo and its so cute and pure I can't handle it. Defo recommend.
For that, I guess you should try searching on the shounen ai tag. I’ve read some decent BL storylines but I always forget the titles. Usually, most shounen ai manhwas have a better ‘shoujo’ like storyline compared to mangas.
Can anyone recommend me a BL manga that's shoujo-esque? Like straight up shoujo but with gays. Though there are abundant BL mangas, I feel like they still are laced with sexual undertones. Something that I don't really see that much in shoujo so I want something that's shoujo x gay agenda.
