This is the perfect show to binge when you're bored and want a thriller or comedy. In my opinion, 8 episodes is the perfect length, as nothing gets dragged on. The story really isn't anything new; it's a typical whodunit involving the staff and customers of a supermarket. What makes this drama great to me is the cast. KwangSoo is KwangSoo, no explanation needed. Seolhyun does an amazing job as well. I love her attitude throughout the whole series. The staff of the supermarket is super intriguing. We do see some development from a few of the employees, which is a nice add on, especially in a short drama. The drama has a bit of misdirection, but about halfway through you'll probably get an idea of who the killer is.
