From what I understand, the reason this isn't updating anymore is because the translators that were translating this, only translated this on the condition that it wouldn't be shared on any manga sites. But since someone broke that condition and shared it anyway they stopped. Now the translators are only keeping their translations private(it used to be open for anybody on their site, you would've been able to find it if you searched well and thoroughly) and you have to have a code to read the rest. The code is open to anybody, but it's a little complicated getting it(especially now). Speaking as a person who has already finished reading the rest of the chapters in volume 2. But you can always try reading the novel, it's really good. The manga has barely reached volume 3 of the novel, there are 29 volumes out and it's still ongoing.
