I'm so confused on what's happening with 2nd couple. Can someone explain to me what their issue is? I dont get it @.@

Ok the second couple have hella slow burn going on but both sides are equally making sense. Guk in some ways wants to possess Nan, he wants to be someone Nan can always rely on (which is why he sometimes gets upset when Nan approaches San hyung instead), in simple words Guk is crazy obsessed with Nan's existence in more than one way.
As for Nan, he needs reassurance (from what I can see from the chapters) and although it appears childish that he wants something like "forever" promised to him, he wants that reassurance from Guk nevertheless. He understands he's being childish, but he still clings onto the idea of that "forever" With Guk i.e Nan wants something that will last forever that he can hold on to (my boi's got issues) while also knowing Guk doesn't really believe in this simple thinking.
All in all, this vaguely sums up their entire relationship. Everything would work out if they just honestly communicated with each other.
What chapter in the novel is ch119 in the manhwa ٩(๑❛ᴗ❛๑)۶
