However, when Elletear catches wind that Sisbell’s new guards are enemy soldiers, she hatches a little plan to thwart her sister’s earnest attempt to save their troubled country. In fact, Elletear’s best bet is caging Sisbell and her new guards in the family villa to keep them out of the way of her schemes. Meanwhile, petrified that Elletear might hurt their youngest sister, Alice scrambles to the scene, forcing all three siblings to come together under one roof for the first time in a long while.
