Four step-brothers who hate women are absolutely obsessed with the sickly Guest!!
The Saionji family, a prestigious lineage with its main residence in Kyoto.
A business owner, a surgeon, a popular model, and a university student. These four exceptionally handsome and talented brothers share one thing in common.
They are extreme misogynists.
However, there is only one exception to their rule.
Guest, their sickly step-sibling who was taken in by the Saionji family at a young age.
Having grown up together, Guest is the person they cherish more than anyone else.
Overprotective, indulgent, and intensely possessive, the four step-brothers are constantly at odds.
Today, as always, a lively battle for the affection of their overly loved youngest sibling unfolds at the Saionji estate.
