In the novel, there isn't supposed to be actual fucking... Just wing fucking. The plot setting is slow in the beginning, but the premise is pretty interesting. Most of the novel is world building and fighting, with the wing fucking being short and happening less than 10 times throughout the novel.
I haven't read the webtoon...
But I recommend reading more to get to the actual plot, because I was also hella confused at what was happening until the big reveal... and then I was like ohh! The beginning chapters are mainly just to introduce us to the schematics of the game, and later on when we find out what kingdom the main character ruled and get past the hatred, then we can see what the actual plot is.
The hatred between in ml and mc will be resolved about halfway through the series.
I'm on chapter 12 and this plot is so confusing is it actually worth the read I was hoping to read less sex scenes and more world building fighting scenes
