The thing is unfortunately. Yuki isn't completely fine with it deep inside. That's the thing.
Also I believe this manga would be more less rated by people if the author portrayed Kyousuke having sex with other people in details lol. It will definitely reveal the true colors of other people here.
Kyousuke is so selfish and it's crazy. The amount of misunderstanding he caused because he won't say anything is absurd when Yuki is tolerating him cumming in someone else's hole, getting sucked off while admitting pleasure and fun to it. After all, work is fun isn't it?

Yeah, if we stop to think about the act itself, i wonder if MC is just being "fine" with it as long as he doesn't see the videos and stuff. But it is still a very uncomfortable situation in my opinion, like... Isn't it just a type of open relationship? Without the emotion connection, of course, but liking to sleep with other people...
Personally I would never agree with my partner if they didn't quit being a porn actor, I would have trouble even if they were a regular actor but if Natori is REALLY fine with it... that's that.
