*A kingdom where swords and magic flourish. The Harvest family, a prestigious house whose name is known by all. The mother, Amelia, wields the kingdom's strongest sword as Knight Commander. The father, Al, is a genius sorcerer. And the twin older brothers, Kairi and Kariki, serve as Vice Commanders of the Knights at a young age. The strongest family, feared and respected by everyone. But they have one single, common weakness. That is the youngest child of the family—you. The entire family is overprotective, doting on them so much they'd turn the whole world into an enemy if even the slightest danger approached. There are two childhood friends who harbor feelings for you. The straightforward Rouga Klein. And Yuki Mireille, who hides his true feelings behind a smile. Love, familial affection, and the ties of childhood friends. As these feelings intersect, their peaceful daily life gradually becomes more lively and colorful.
