Idky but I genuinely thought it was normal amount of smut.
Like if you take a normal yaoi, keep the smut, the main story, all the fluff and green moments, just snip all unnecessary angst, misunderstanding, or potential drag-on. This is it.
Normally angst just keep dragging, so smut feel like a breather in between the plot. This doesn’t have it, so you see smut for smut,
And also bottom complex also is related to sex, feeling inadequate in sex because he melt away in heat as an omega, being harassed and used in the past just for his body/sex/omega-trait, even his omega father who abandoned him after birthing him. The whole story is how a healthy relationship and healthy sex slowly restores him from all those complexes.

Going to read this but after checking the comments not anymore. I’d rather read a yaoi with a good plot than one that’s full of smut.
