This happens on this site sometimes. The original upload of the chapters was named incorrectly. The upload on here labelled "Ch 1" is actually chapters 1-4, "Ch 2" is 5-8, etc.
Somebody came back in and saw that it was up to "Ch 15", found Chapter 16 and started updating again, not realizing that their Chapter 16 is way back in "Ch 4" of the original uploads.
I have no idea if there are updates past what we had back in 2018, so I wouldn't get my hopes up that we'll actually see anything new when it catches up.
Hi, I'm the translator. I can't control the updates on this site. Yes, they started uploading from ch 16, but I'm dividing the chapters the same as the Spanish version (from where I'm translating).
So the manhwa actually finished. I'll try to translate everything (so past the part where the previous translation ended). I only hope they won't ask me to stop (that's why the previous group abandoned the project)
Oh okayy I understand
The same chapters?
