I've read a lot of manga/hwa/hua with similar premise of confinement and mind break like this one but personally speaking, nothing beats Harada sensei's mangas with these type of stories. It's not about how dark the story is, but the process on how the aggresor slowly breaks into the victim's mind, this is what I find lacking in most stories, just like this one.
Here's one that has similar premise as this story (kidnapping&confinement): Gintama dj - Mienai Kusari
If you are fine with reading fanfics you can go ahead with this one. It is also a short story but the delivery of the plot is really good. Just be aware that it can get more disturbing, disgusting even, as compared to "Tosa's Master".
Honestly, I'm starting to get bored with this. I'm already used to reading dark shits like this one so all the fucked up things shown are still within my tolerance but the recent plot "developments" is starting to bore me. I might just wait for this to end before reading it (though I know the ending already based on the novel).
Ah ah just when I thought I could finally a threesome story with an alpha beta and omega but this turns out to be more of a love triangle
someone please give me some recs with AxBxO dynamics where the three ended up together or maybe an alpha with two omegas or betas (this would be very interesting to see for me lol).










Lol I feel sorry for the real estate agent, he was probably very happy at first to have a rich client without knowing that a deal will never be made with Ash smoothly nitpicking everything
