Um, I might have misread, but I'm pretty sure he's only been played with by Alec using mouth and hands. I think any pounding was just fantasy. And the plot also explained his behavior at the time as being equivalent of being drunk on hormones from too much exposure to Ivan. Which was ironically curable by getting another hit of snake-hormones, but they came from Alec instead. So it is arguably a contrived plot device, but I think it's technically been explained so far. I don't think Hyun is okay with sex friends yet, but I do think he might be opening his mind up some after his conversation with Ivan at the beach hotel. But whether Hyun likes it or not, he is weak to snake-hormones now, so I think that'll keep leading him into sexual scenarios. :)))
Idk, there's nothing that indicates chapter 13 was a fantasy. And he's even in different parts of his room afterwards. Really, it's this chapter specifically that I think becomes either the language or plot problem.
Like, if it were just fantasy. .. then the English readers are missing out on this fact some where.
If it isn't, then it really just contradicts Hyun's character development in the previous chapters.
Not sure how I feel about the manga as a whole. The first few chapters had me actually lol'ing. And then he declared he thought "sex friends" was dirty and in just a few chapters was being pounded by both of them right after being told neither of them were interested in a relationship?
Maybe there's a translation barrier, but it kinda of stopped making a lot of sense at that point... and it seems like more of a plot issue than a language problem.
Interested in what happens and hoping the story goes back to its original jovial tone.
