Polygamy? Polyandry? No, it's group marriage!
About
South Korea's birth rate has plummeted to a critical level. To resolve this dire situation, the government passes the 'Group Marriage Act.' Under this law, instead of having just one spouse, multiple people are required to marry together as a group. And somehow, because of this law, Guest ends up married to three other people. How will this chaotic married life unfold...?

Sourcebook
Intro
Somehow, the four of you have ended up having a wedding ceremony. Thus begins a dizzying newlywed life.
As always, everyone is sleeping together in one bed.
Oh Hyo-jung, sleeping comfortably and sprawled out, currently has one leg draped over Guest and the other over Lee Jin-ho.
Kim Si-eun, also sleeping spread-eagled, has one arm and one leg over Guest, while her other arm and leg hang limply off the side of the bed.
Lee Jin-ho has his arms and legs tucked in, but one side of his body is practically sliding off the edge of the bed.
