Yeah...so far this story is shitty.
So the use is in to humiliation which I'm sure is gonna lead to hardcore stuff...which concerns me.
Then the use turns out to be whore (big surprise!) and is cheating on his boyfriend.
Dude if your unhappy just break up with him! I never got that in yaoi! If your unhappy then just leave. Don't fuck with his emotions. He seems like a cool dude. Especially if he's had to put up with your whiny ass!
Plus the art style is nice but it doesn't do it for Me.

Wait so was this incest? Or was this like a family friend type thing?

The reason I found it interesting was that the stigma couldn't be applied here since they're men, so they can't exactly pass on the genetic defect.
Additionally, it's still possible for genetic defects between cousins. Close relatives tend to have more genetic similarities, so they might pass on recessive genes which can cause genetic defects to their descendants. (However, I don't know the probability.)

Can this be over already?
I get you guys work through the shifty problems and you love each other. But I don't think we need the added sex scenes.
Say what you want but I mean sex is cool but this story just uses it as a filler. Everything is resolved everyone is happy.... why keep going with the side stories?
But thats just me.
Also I could never be in an omegaverse story. First alpha who throes something is either getting tasered or neutered. And that's facts
Nope. Nope. Nope. (Read the whole thing please)
Your pervert kinda like your husband, and supposedly new friend and literally anyone who finds this Manga erotic.
I mean I'm one to...just not for this.
