It's about two old gentlemen and their bastards, about the dreams of little people in the city, about extraordinary life, about decadence and passion. One is a sultry electronic guy with glasses, and the other is a literary and awkward folk guy. What will happen if two old and decadent old gentlemen get passionate? In another corner of the world, their children are also running on the road of chasing their dreams - a technological two-dimensional otaku girl, a dead-rational and warm-hearted brother, and a literary young man with an athletic waste. When they begin to explore the world and meet each other, what kind of strokes will they make on the canvas of their respective youths? When the interest of science and technology, the richness of folk customs, the sickness of otakus and otakus, and the decadent passion of the dissolute old gentleman all come together?
