the novels i listed are ongoing
How a sidekick prince lives again ABO historical went back in time
Circumstances of a fallen lord historical i think no ABO but really nice (i think it has a manhwa already but reading it is really great)
Turning is nice (it's beautiful ABO but they're Awakeners, it has time travel aspects as well)
The Show must go on his. historical fantasy reincarnated no ABO
where the MC is a villain. kinda dark cause he did a full on revenge for her daughter but it's nice (you go to the translators website and/or join their discord it has the link to where it actually is. they had to share it discretely like the rest of their work but it's great nonetheless!
have fun reading
ah the show must go on is actually completed with a sequel which is also good as well that's called the forbidden fruit... beautiful
any rec like this BL, historical + omegaverse, its ok if its novel too
