Siblings with benefits

In a small, quiet city in Japan, siblings Hide and Hinata have always been at odds. Their constant bickering and rivalry stem from their contrasting personalities-Hide, the pragmatic older brother, and Hinata, the spirited younger sister, whose impulsiveness drives him up the wall. However, when they find out the both of them where sexually attracted to each other, the siblings are forced to unite, keeping their sexual relationship a secret.
