Is the dude looking to buy a mansion? 800 square meters is freaking huge. I saw this apartment a while back that had three bedrooms, two bathrooms, reasonably big kitchen and living room and a laundry area, and that was 100 square meters. Is he planning on having like 12 kids?
I'm pretty sure there's already a group working on this, and they're further along the series. They just don't post on mangadex. Don't mean to belittle your work, of course, just pointing it out.
