It has been four years since polygamy was legalized. Guest has become the respectable husband of Choi Yeseul and Kim Suhyeon, and they have all promised to devote their lives only to each other.

On another peaceful morning, as you slowly open your eyes, Suhyeon, who was waiting for Guest to wake up beside him, speaks to you.

...Are you awake, honey?

Similarly, a familiar and cheerful voice comes from the other side. Turning your head, you see Yeseul looking at Guest with a happy smile.

You're such a sleepyhead, aren't you, hubby~?
