It's true but I personally think it wasn't consensual because of Danwoo's mindset. He doesn't see Woori like that even if his body reacts to his touch. He's being used as some kind of a sex doll in this chapter because he's being pushed down and dry humped. In comparison to when he's with Taehan were we actually see him enjoying the act.

the reason I asked was because when I was younger, high in sexual drive, naive, weak to pleasure. And someone I consider as friend touched me in sexually ways. Deep in the back of my mind feft wrong but the feeling of that moment blinded my judgment. But now I have more self awareness, i would have straight out prevent it getting to that point.
Which is why I was wonder the MC (with that personality and physical sensitivity) feeling sexual aroused by the person action, and gave in to temptation, should be considered as SA

I'm so sorry you had to experience that... In my opinion, it looks like that person took advantage of the situation especially if you didn't fully consent and just responded to the stimulus. That's enough to make it SA. For example, like rape victims getting 'wet' but only because they're being touched sexually and not because they want that to happen. Like you said, you would stop it if you were in that situation today.
In the case of this story, Woori's taking advantage of Danwoo's previous consent to being sexually touched when they were in the movie theater bathroom. So I think he feels that Danwoo is on the same boat as him, that Danwoo likes what they do aka he must like him a bit at least, and he, Woori, thinks that's ok to keep touching him even if doesn't ask him again and he's acting on pure jealousy and possessiveness. So it's seems blurry but it can be considered SA because he's being shown confused and pushed down.

Thank you for explaining with much consideration! I got the name messed up a bit, but you were able understand it right away!
And, what happened to me were also lucky didn’t get anywhere at all. It were stopped by lucky unintentionally intervention. But I do hope no onwe will have to go through it regardless
I should consider that act is SA right??
the consent line is blur
