Pen the penguin lives with his most favorite keeper in the world: Hayakawa the human! But Pen's no ordinary penguin - he's a neat penguin! A proper penguin! A doting penguin! Pen loves to daydream of Hayakawa's smile as he flips pancakes, runs errands, and folds the laundry with his teeny-tiny flippers. If only his beloved Hayakawa would notice! Unfortunately, Pen's human keeper can't speak penguin and is also a hopelessly lazy university student. With Pen's comical expressions and Hayakawa's lighthearted cluelessness, every day in their house is full of adorable mishaps and hijinks!
