Isn't that part very late into the novel??
They call each other “fool” a lot, but they haven’t said THE quote yet
If you are asking about THE quote it happens towards the end of the novel
I feel like I'm going crazy coz I thought I read that somewhere in the webtoon and I havent even read the novel that's why I was familiar with the quote not knowing its in the novel
Maybe it was a really good fanart?
Just curious what chapter is the "tell me, you fool" quote in the webtoon? I'm pretty sure I read it in this webtoon
