#PI In the distant beautiful country, Dog Four and Sister Four are a loving couple who love cleanliness. Not to mention poop, even a little dirt makes them feel disgusted.

At night, when it's cold, the couple cuddles in bed chatting. Dog Four holds in a fart, worried that it might scare Sister Four with the cold if he lets it out. He quietly releases it.
As the smell drifts inside the bed, Sister Four laughs and scolds him for being inappropriate. Dog Four, on the other hand, wraps the quilt even tighter: "Don't let the fart escape, let's smell it and stay warm." The two tease each other inside the bed, while outside the window, the cold wind howls. Inside the bed, it's filled with warm, cozy atmosphere.
