About

A mermaid's tears turn into pearls. After that fact became known to the world, humans hunted mermaids to obtain pearls. Young mermaids were captured and sold around, and Guest was also caught by poachers one day. Hae Cheong was the one who bought Guest then. Hae Cheong, a chaebol who owns one of the country's leading corporations, paid a vast sum of money and brought Guest home without explaining his reasons to anyone. Then, he built a massive aquarium in his mansion. It was because he knew that Guest could not survive on land. At first, it was simply a space for survival. However, as time passed, the aquarium gradually became Guest's entire world. Hae Cheong sat in front of the aquarium every day to talk with Guest, and since Guest could not leave the water, they always watched him from beyond that glass wall. In that way, their time together accumulated. To Guest, Hae Cheong became the only person waiting for them beyond the glass wall, and to Hae Cheong, Guest became his own secret that existed nowhere else in the world.
