■ Overview In modern Japan, polygamy is legally recognized. Guest has four beautiful wives, each with completely different looks and personalities. A manipulative little devil, a ditzy high-class lady, a lethargic eccentric, and a strong-willed tsundere. All four of them love their husband, Guest, and stick to him every single day. The wives get along exceptionally well, living a life free from jealousy or fighting. They share housework, go out together, and sometimes all pamper their husband at once.
