I find the sex scenes extremely sexless in a weird way. Idk why, I do find the characters hot when they're serious or intense about something, but when they're naked and fucking, it's like watching a piece of ham being slapped around. Guess it's either the art style or how they're both extremely muscular yet hairless haha.

Its cuz they havent connected mind body and soul AND heart. If you check author's previous work Full Volume, the sex scenes work when the peepo are obsessed with each other.
The sex scene weve witnessed here was mindlessly intense but it lacks passion and love. Its an intense need to treat an animalistic aching, its focused on mating and populating, not sensuality and the need to pleasure a beloved and reach orgasm together. Basically: mindless, animalistic and still needs a lil cooking between god and his sacrifice (づ ̄ ³ ̄)づ

Guys the whole story is about his abandonment and attachment issues Like if you took that away from him, it's a story about nothing. God forbid we have interesting characters.

I don't think it's a bad thing, because it's not like it's shallow. It really explores his perspective, how he became that way and how it impacts others in his life. It makes the characters feel more like people.
My point is that if a reader just wants to see two hot dudes kiss with no issues whatsoever, then go read thaaaat. His issues aren't a fault, they're a feature!
And the award for the most out of touch story of the century goes to!!!!
Seriously, I don't mind turning my brain off for these sorts of things. Host club story? Sure, I don't care that it's an industry where sex workers cyclically emotionally manipulate each other into debt, it's just a story. Medieval master/slave story? If their dynamic and themes of the story are interesting enough, I can turn off the part of my brain that wonders how the rest of their world works. Yakuza story? Well, the aesthetic of an honorable yet dangerous institution are cool enough for me to stop thinking about how they actually make their money and how it impacts their communities.
What pisses me off is how...cute it's trying to be? Nobody would have given a shit if it was mindless porn. Nobody forced the author to give their human trafficking smut manga an uwu kawaii spin. Oh, the dude that went to buy a literal human being was moved by how the overseer gave the product a fucking blanket??? How nice.
If I'm making a larger point about BL manga in general, the thing that breaks my immersion the most is the crossing between cruel and wholesome motives. If I'm reading a fucked up story, I'm not clutching my pearls when the characters do horrific stuff to each other. When I read Harada's work, I can't really make any assumptions about the author, except that he likes writing dark fucked up stories.
HOWEVER. If I'm reading a "wholesome", "green flag", romance manga and in the mid point of the story main love interest assaults the protagonist, it's worse. Even if it happens once and they're fine together afterwards, just by the mere fact of including this horrible thing in an otherwise cute manga, it becomes more fucked up (to me) than let's say Killing Stalking. Because at least those sorts of stories never tried to make you think that they're picturing the ideal couple, a relationship to root for. I do start to make assumptions about the authors, that they're either so sheltered that they can't differentiate between which "yaoi tropes" are good for their story and which are not, or that they simply consider this to be an okay thing to do in a relationship. It's extremely easy to notice once you start paying attention to it, how often the protag can literally be crying "no", "stop", "it hurts", only for it to be treated as "geez, they sure have a wild sex life!".
Back to the point: This could've been a fucked up porny manga. Instead the author decided to make this story as sympathetic to it's rotten core as possible. It didn't need to try to make the protagonist a good man, as that's impossible with what his job is. It didn't need to try to justify itself as it unjustifiable. By painting over the horrific setting with the visual language of a student romance, this story is way less interesting and way more cruel than it ever had to be.
