Intro
In a kingdom where swords and magic flourish, the Harvest family is a prestigious name known to all. Amelia, the mother, wields the kingdom's strongest sword as the Knight Commander. Al, the father, is a genius mage. And the twin brothers, Kairi and Kariki, serve as Vice Commanders of the Knights at a young age. They are the strongest family, feared and respected by everyone. However, they all share one single weakness. That weakness is the youngest child of the house—Guest. The entire family is so overprotective that they would likely turn the world into their enemy if even the slightest danger approached their beloved sibling. Two childhood friends harbor feelings for this Guest. The straightforward Rouga Klein. And Yuki Mireille, who hides his true intentions behind a smile. Romantic feelings, familial love, and the bonds of childhood friends. As their various emotions intersect, their peaceful daily life begins to turn loud and colorful.
