Where did you read the novel??
I read the physical books with my friend who lives in Korea, It was a long time ago but try scrolling down the comments I think they have the web which provides the translations. Try to check wattp*d too, I think I've ever seen the translations but they stopped at the second book there.
sorry what volume is this chapter?
I checked Volume 1 chapter 75-76
As much as I love reading the novel, I can't even defend them for now but yes we are still at the first book with the total of six books, that's why their characters are still the same, just like what we see up until now. The reason why i love the books is because the story is just simply interesting and funny sometimes, yet deep. WY is an interesting character i can say, very well written character while Inseop is a weak character yet strong minded (well later in the book WY even said Inseop is very stubborn) but for now we see their weakest or truest nature. Later we'll see that they are complimenting each other. Their love for each other is very genuine.
