You should read Full Volume again ( ̄∇ ̄")
Romantic and non-toxic? MC was manipulated by the adults around him and stayed in the sex industry not bc he wanted but bc he was gaslighted into it. Nearly raped a couple of times. ML was nice but so is Mugo/Muhan here. Both mcs suffered as much as jesus christ ("-.-)
The person you’re replying to literally specified that it was non-toxic FOR THE COUPLE. Not the other people who interfered with the ml and the industry he was in. But that’s different in this story, like in the most recent update he forced himself on Jae-Heon because he felt entitled to him. It’s a completely different concept from full volume but something that happens in many Omegaverse stories. That’s what they are trying to say.

"Full Volume" was so romantic and non-toxic (at least for the couple), but then there's this. As with most omegaverses, it has toxic stuff, but the backstory really made me dissatisfied. MC was a surrogate for ML's uncle, but then ML just decides to claim him and doesn't really try to understand ML's feelings and disgust for alphas (or sols, as they were called back in the day). Losing interest, not matter how sexy the art is.
