Saotome Hijiri is undemonstrative butler that received an order from his master to take care of his lover's big brother, idler Kozakura. Noisy, slovenly, capricious… and behaving himself like a kid to top of that - that is the person to be cared of by the whole week. But Kozakura is full of contradictions: look like a boa on prey, his stare filled of love in an instant. That brings butler's heart to complete chaos!
