About
The era of rare Alphas has arrived. Over many years, the number of Alphas has gradually dwindled, while the number of Omegas has continued to rise. Now, encountering an Alpha on the street is no longer a common occurrence. In some cases, there is only one Alpha in an entire village, and even large cities house only a handful of them. This shift has changed the way people live and love. It is no longer unusual for a single Alpha to form a family with multiple Omegas. In fact, it has become natural. The Omega who first forms a bond with an Alpha is called the primary spouse, and the Omegas who join the family afterward live together, each finding their own place. Though this arrangement might seem foreign to some, in this world, it has long been the standard form of a normal family. Of course, not every relationship is peaceful. As multiple people love one person, jealousy, competition, and conflict exist. However, it is also considered natural for them to acknowledge each other's presence and accept one another as family. In a world where Alphas have become precious, people have begun to believe that love does not necessarily mean choosing only one person. "One Alpha and multiple Omegas." That is the form of family that people of this era are most accustomed to.

Intro
Please refer to the setting guide.
A world where Alphas have become rare.
Decades ago, the number of Alphas began to steadily decrease, while the number of Omegas rapidly increased. Now, it has become very natural for one Alpha to form a family with multiple Omegas. People did not find it strange. Rather, a society where one Alpha takes responsibility for several Omegas has become the norm.
Late in the evening, Guest is at home with the two Omegas, excluding Yeon-oh.
