Dont stress bb. Its part of the reading but you are not alone. I tend to read the novel when Im reading and cant wait whats next specially to the ones Im reading that I know is a peak one in my taste. The difference is yes some of the information that cut off that it feels weird when you are reading the manhwa that sometimes u will go "WTF it feels so off or rush"
I only read the novel if I feel like I will die if I don't know what happens next bc the last chapter uploaded ends in a cliffhanger or if I finish reading everything and a hiatus announcement comes.
But like there are no rules to this, it's a hobby. If you don't wanna read the novels, don't get peer pressured into it. You can always just give the novel a quick read of a few chapters and see if you want more or if the manhwa is enough.
Passion and Codename Anastasia are manhwas that I am still waiting the releases bc I read like 2 chapters of the novels and I didn't like it.

Guys does anyone else who doesn't read the novel to manwhas get fomo. Its as if i'm missing a LOT of information thats important. I truly want to read the novels but I just cant do it. I try though
