A pair of completely naked girls are whispering to each other, murmuring about the women in the pond across from them. These long-haired women, entirely nude, strike seductive poses. Bizarre giant beasts, shaped like male genitalia, carry "castles in the air" of various designs on their backs. They comment on each woman, drooling over the beautiful and enchanting ones while ignoring or even despising those with ordinary appearances. Similarly, the women measure and judge these giant beasts using the same method. What they care about is nothing but the "castles in the air" on the beasts' backs. The first beauty chooses a precious mansion adorned with carved railings and jade ornaments; the second woman chooses a "handsome man" with delicate features... The remaining spots grow fewer and fewer, leaving only the short and plump girl alone. The girl who chose the "handsome man" enters an extremely prosperous yet decadent world, boasting to the plump girl about how extravagantly she spends money. In the end, the plump girl, neglected by all of this, rows a boat alone, watching the women on the shore live their so-called happy lives.
