You know it was already announce it was the last volume right ? We have like 3 chapter left.
Obviously, no, I did not... ;_;
Can we maybe possibly hope for a sequel with these characters/couples? (Or is the author really ready to move on? which would be understandable too, I guess...)
...so, 3 more chapters... well, it's been a nice ride so far, so fingers crossed for a great ending.
I wouldn't bet on the mother being a huge problem just because she called her kid home who ran off late straight from her job. Maybe she just wanted to preach her something about responsibility, closing the shop properly and actively telling someone where she goes instead of accidentally bumping into her sis on the way out...
I would, however, imagine some sort of sisterly teasing to come up. Maybe even her outing her little sis totally casually at dinner...
