Not bad. Very typical story, played very straight, but I've really been into these "young of-age daughter is treated like garbage by her family and is sold off to high-ranking "cruel" husband" stories. My Happy Marriage from this season ofc, but also just coming off from Busaneko not too long ago.
Yeah it seems the scanned pages are stopping mid-chapter with the next one. It's the same with 2 and 3. There might have been an upload issue or the file saved more pages than needed.
