Old-Fashioned Cupcake

At 39 years old, Nozue lives a routine, if not melancholic, life of sleep and work. Togawa, his younger subordinate, finds it troubling and takes it upon himself to shake up Nozue’s routine. During a lunch outing, the two go to a pancake shop full of exuberant young ladies to "do what girls do," and it’s just the thing to breathe life into Nozue. The two men start an unlikely friendship—and perhaps something a little sweeter!
