When both are onboard with it. There are so many supposedly-green ones out there that are ruined by non-consensual somnophilia. Where the assaulters hide their action from the other party because even they knew it was wrong and shameful. Just look how shameless Jake is!
Shutline is a dark romance/kink-heavy manhwa and there is a massive difference between a boundary violation and a shared, premeditated dynamic.
Shin and Jake have actively built a relationship where their "freak flags" are out in the open. Shin's craving for Jake’s intensity creates an unspoken, ongoing green light for these specific boundaries.
Jake knows exactly where Shin’s lines are drawn and this scenario stays within the realm of their mutual desires rather than crossing into actual assault.
We all know how stubborn and strong Shin is, do you think he'd not raise hell if he found out about what Jake did and he's not into it? Look at him, after Jake has told him about it, look at what his actions were. Our guy was turned on even more. This is Shin we're talking about, the exhibitionist Shin.

Okay, I wanna say something about the SA while Shin was sleeping, as some people mentioned it, and honestly I was happy to see such awareness. (Sorry if I can't break this into paragraphs because for some reason, my whole comment isn't getting uploaded fully if I did so).
I have always been labeled a moral police by calling out such scenes so why am I not doing it here? Am I biased or a hypocrite?
I don't think so. If you're a reader of this manhwa, you'd know by now what Shin's and Jake's kinks are and how much they accept (and love) each other's freaks.
Shin knows and accepts Jake's "obsessive" tendencies and perviness, he even craves it. You saw it time and again, and in this chapter as well.
You saw how Shin was totally onboard and Jake wasn't even hiding it, because he won't do something Shin doesn't and won't like.
This is how you do the sleeping beauty kink! When both are onboard with it. There are so many supposedly-green ones out there that are ruined by non-consensual somnophilia. Where the assaulters hide their action from the other party because even they knew it was wrong and shameful. Just look how shameless Jake is!
