Well, I would say he was probably semi-passed out rather than sleeping. SH the beast must work him all night when they are at it and NK barely recalls what happens afterwards xD! I also loved the shoes panels. How sublte and beautiful *-* As for the last part of your comment, I believe Inhum, SH's young brother and all the drama related to his father would be addressed in a another season(s). The author is just throwing some information here and there to enhance our interest. She said in one of her interview that she wants to write a quite long story so I am expecting at least 4 seasons... hence the slow plot progress.
Okay but how someone sleeps through being place in a bucket full of water?
Although this scene fits nicely with the one from previous chapters where Seungho is seen carrying Nakyum all wrapped in a blanket. (The one where the merchant thought he was carrying his 'fiancee').
The scene with Nakyum caressing a sleeping Seungho is warm and maybe it's just my imagination but sometimes it seems the author is intentionally and subtly drawing Nakyum looking 'bigger', less of a boy and more 'mature' as part of his development too as maybe another symbolism that his stature in the relationship is changing from lowborn/servant to equal.
The other scene I live is Nakyum sitting outside having Seungho's shoes by his side. To me, yet another symbolism of them becoming a couple and slowly establishing that, at least between the two of them, the lowborn/master hierarchy is being broken (they face every outsiders norm though).
I know Jihwa and the unwashed version of Seungho or Tarzan like he is being called now ( lol, love that) are popular but gosh, at least to me, those are the parts that I am least interested.
I think I am kind of old fashioned and I think stories with a main character that are already hard to like or root for like Seungho should maybe not introduce side characters that may overshadow or take over. The new hunk doesn't need to have anything interesting or a background story, just be the kind of fanservice eye candy these characters are and not be the 'rapist' to automatically be granted status of male lead and although I understand the pressure on the author to give readers another version of Seungho they can root for ( because I'm sorry, that's what the new guy is, Seungho's less evil twin), I can't help but think this undermines the main story since a lot of times fanservice characters become more popular. The chapters being so short in this story really doesn't give much chances for all the characters to be well developed and in the end we may end up with the main couple side stepped or diminished to make space for Jihwa and his Tarzan (like it's already happening) that probably may become more popular since they don't face the obstacle of a rape plot curve.
Lost in this also is that the story still has so many side characters that now just got their chances for a better development diminished, like Seungho's brother. Inhun and his arch and whatever is Seungho's relationship with his father. I like the story but I can't help to think that Jihwa and Tarzan will start to eat up all that once the author starts feeling the appeal to please more and more the fanservice linked to the hunk.
