It's actually a good one if it wasn't for Cha Soo Bin's acting. The plot is average. The kind of predictable drama that you would just binge-watch when you have nothing to do. But I see it actually as a waste of time. I watched it for Go Kung Pyo and Kim Seon Ho but I was decieved with the rest. It's quite original for the fact that it's a story about deliverymen among all other jobs and it was quite funny at times. Give it a try if you like Cha Soo Bin. But I would rather recommend that you watch "I'm Not a Robot" instead it's a hundred times better.
