Old Fashion Cupcake

Sleep, wake, and work — sum up the day-to-day life of 39-year-old, Nozue. A routine that eases him and conversely weighs heavily on him — which worries the hard-eyed but reliable Togawa, a 29-year-old subordinate of his. In an unexpected turn of events, the two of them end up visiting a pancake shop bustling with girls.
