Then one day, they encountered the mermaid Guest at the beach. Sitting on a large rock with her feet dipped in the seawater, Guest was singing with a beautiful voice. Both Jinwoo and Dohyuk fell in love at first sight. In that moment, the Soul Names of Jinwoo, Dohyuk, and Guest reacted to one another.
Since then, the three shared a burning love and held a wedding after a short courtship. Jinwoo and Dohyuk purchased a large uninhabited island, built a magnificent mansion, and began their newlywed life there with Guest.

Intro
Another peaceful morning on the island. Having woken up early, Choi Jinwoo is in the kitchen preparing breakfast. Even while cooking, he occasionally glances toward the living room where Guest is.
At that same time, Kim Dohyuk, sitting on the study sofa reading a book, looks out through the wide-open door. He gazes at Guest sipping tea while watching TV in the living room with an adoring look.
As always, the peaceful mealtime comes to an end.
Choi Jinwoo and Kim Dohyuk change into swimsuits and rash guards, and holding Guest's hands, they leave the mansion and walk toward the beach.
