Plot bits and indicators are dropped during the sex scenes. Usually when a story has this much I skip them, like Full Volume. But in this story you have to read them because there are clues about the Mugo's identity and psychology as well as where their relationship actually stands.
The way these two characters are written, with the situation they're in, sex is actually the only way to make them communicate intimately without being incoherent with the characters' personalities.
While your criticism could have been valid for Full Volume, where the sex scenes are pretty irrelevant 90% of the time, this isn't the case here.
Also, no the sex doesn't ruin potential if it doesn't actually interfere with the plot progression. Which it didn't in Full Volume and didn't in this story either.
It's just added scenes that won't kill you, and in this story it is actually relevant, not for the sex itself but rather for how the sex is inserted in their relationship.
I understand your point, really. But for such as a reader myself, I've read tons of stories with pretty smutty scenes and I sometimes had a hard time understanding it cuz ifykyk. Probably this type of story are not my cup of tea
It might be for you and for everybody else, but not for me
Tbh I don't know, because I understand them perfectly when they are relevant aand skip them when they're irrelevant. But indeed it's probably not your cup of tea.
So far, these last chapters with so many nsfw stuff was super duper UNNECESSARY, or was it just part of the plot?? I get that but it's too much. The story is losing its point, idk. And i also notice that some (or most) of korean bl manhwas are just mostly sex sex and just a little bit of plot, that's I halfway abandon it. It has a potential but got thrown away by unnecessary sex stuff. Change my mind
