im arguing against your point that it's what it says on the tin, when you're reading the first chapter you don't know bro's being raped. it's also generally pretty distasteful to include rape porn in anything, even if it's plot convenient. it's normal for people to get grossed out at it. personally, i skipped the whole thing.
Dude you skipped it bc you know hes being raped lol, dont be dense saying that the reader wouldn't know, what a contradiction
Im not going to argue about plot convenience, bc its the eye of the beholder, think about it too much & every action will turn into a plot convenience.
I can kinda of agree on the distasteful to an extent. Having it fully shown from beginning to end is the distasteful part, but some stories I can read with it because in the end, it's fiction, bad things happen in stories.

when I just started liking this this manga, then suddenly the author uses r*pe for plot convenient sake again, don’t u have any other creativity huh??!! Ts pmo
