Idk if it's just me but it feels like there's so many missing chapters In this

where you reading the official translation?

were*

Yes.

I think it's the translation that made you feel like they were missing a chapter. I don't know; personally, I think the official translation isn't really good. Like what the other person said below you, the translation feels pretty awkward, with some words that don't fit in the dialogues. The unofficial translation (translated by a scan group) sometimes doesn't make sense either, but the unofficial one is way better than the official. I still had to read both the official and unofficial versions. Also, at the end of Chapter 15 in the official version, it doesn't end at that panel—there are more panels missing (and the missing panels in Chapter 15 aren't the uploader's fault because it's the same thing on the official platform).
