I just started it so lemme get this straight, J was a kid back then too? Somehow he went into a gate and time travelled 8 years into the future? And it's not a case of adult regressing into a kid's body?
J was a kid back then too yes, in the novel he was extremely young when he first became a hunter, so after 8 years passed his body did not age in the dungeon, but technically since the time passed anyway he would be about 28 right now and Sayoung would be 24. There is no regression in this case, I don’t wanna go too into detail about it because it a major spoilers! Don’t quote me on the exact ages though it’s been a while since I read the novel
I lost this one from my lists and no wonder I couldn't find it any sooner since it's not updated for like a year ╥﹏╥
