Are you using KKP app? If so, the novel only has a 1 day wait time to unlock 1 new chapter for free and will be available for 3 days before it's locked again.
It's my first time translating and there's a bunch of things I don't know, so thanks for telling me about this! I'm having some trouble logging into the app, but I should be able to figure it out. Edit: Apparently I was trying to use a partner app, which doesn't have the novels; the actual app isn't available in my country.
If you're on android just search for kkp apk file, download it & then install. That will work. For ios, this is just from other people guide, you'll need to tinker with the region setting, fill out made up info (post code would be better use any real s. korea one you could find on google) but with your real phone number & then you can install the app.
