It's already licensed by Renta in English. That's why the uploader always noted to support the mangaka in renta. You should check that too. Great collection.
I already own all 6 episodes I bought them on Renta I started reading it on Renta before it was uploaded here But Renta hasn't uploaded the manga in a month and there's still 3 chapters left. Everyone here was wondering if the manga got dropped since this can't be uploaded either until Renta puts out the last 3 chapters or someone buys the last 3 and translates them.
I'm so sorry that I thought you haven't check there on Renta. Since we don't know the team of the translator, why don't you or we try to ask regarding this manga to Renta. I asked Renta using twitter DM couple of times regarding the apps and they replied. Maybe they can answer too about this. I just hope they're just on hiatus with this series and thay they stop translating not because they found the translation are uploaded in the manga reader like this.
I didn't even think of doing that! Thanks for letting me know I'm definitely gonna ask cause I want more of this manga. I hope so as well I really want to see the end of this series it's one of my favorites.
There are at least 3 other chapters you can buy them here

They aren't translated though which sucks we just have to wait for the English translators to finally translate them. (╯°Д °)╯╧╧
