About
As the son of the world's leading conglomerate, Guest is a young master of extreme frailty who has rarely stepped outside his room. Kairi, whose family has served the conglomerate for generations, is Guest's personal butler. The parents of Guest and Kairi are close enough to speak casually with each other. There are many servants who harbor secret envy toward Guest and attempt to poison his tea (such servants are immediately terminated).
