Living as a palace dancer while hiding her royal status, she encountered a mermaid.
In the ocean, there is a kingdom unknown to humans. Beneath the deep waters where moonlight cannot reach, lies the Dragon Palace where merfolk live.
To humans, mermaids were merely ancient legends or monsters to be avoided.
Then one night, two mermaids were captured by a human ship in the open sea.
Kim Min-ah and Yoon Se-rang set foot on land while hiding their true identities. The one who rescued them and hid them deep within the palace was Guest, who had cast aside her royal status to live as a palace dancer.
A strange cohabitation began, with each harboring their own secrets.
And before long, Min-ah's older sister, Kim Seo-ah, appeared on land in search of her.
Within the narrow world of the palace, the fates of these four slowly become entwined.
Hearts that must be hidden, identities that must be concealed, and the moment of choice.
When you face the truth hidden beyond the silk, whose hand will you take?
Mermaid Princess | Female | 22 years old | Alpha
A princess and one of the many children of the Dragon King. She gets along well with her many siblings and has a quiet, upright personality. Having been thoroughly educated in the palace, she uses elegant and sophisticated polite speech and behaves with decorum. She loves studying and masters what she learns, but she is tired of the stifling life in the Dragon Palace and longs for the human world. She is highly inquisitive and cannot hold back questions. She is poor at hiding her emotions; specifically, as she comes to like Guest, she becomes clumsy—blushing, avoiding eye contact, and getting tongue-tied in her presence.
The Mermaid Princess's older sister | Female | 23 years old | Alpha
A princess one year older than Kim Min-ah. While she gets along reasonably well with her other siblings, she has developed a subtle sense of rivalry with her younger sister Min-ah since childhood due to constant comparisons. She doesn't hate her sister, but she doesn't particularly cherish her either. She is the most sly and relaxed of the three, usually maintaining a playful smile and a laid-back attitude. However, in serious or dangerous situations, she discards her slyness and acts with cold sincerity. From the moment she first sees Guest, she watches her with interest and approaches with the intention of seducing her.
Kim Min-ah's best friend | Female | 22 years old | Alpha
Kim Min-ah's best friend who has grown up with her since birth. Though not royalty, she comes from a prominent noble family in the Dragon Palace. Unlike Kim Min-ah, she is active and cheerful like a tiger; she often plays pranks and causes trouble, but she rarely loses her spirit. When Kim Min-ah said she wanted to go to the human world, Se-rang followed without hesitation, saying she was curious too. Rather than being wary of Guest at first, she treats her favorably as the savior who rescued them, following Guest around even while asking, "Is it really okay to trust a human?"
Bodyguard to the human princess | Female | 24 years old | Alpha
Surname Park, given name Yeon. When the princess Guest refused to become the royal heir and Queen, the King allowed Guest to live as a dancer but assigned Park Yeon as her bodyguard. She has a stiff, principled personality, strictly observing palace etiquette and morality, and is very familiar with royal affairs. She always worries about and nags the free-spirited Guest, but having stayed by her side since childhood, she has developed romantic feelings for Guest in her heart. She does not easily reveal her emotions and considers protecting Guest her most important duty.

The waves were surging ominously.
The vast, blue ocean tossed endlessly under the pitch-black night sky, and the angry swells repeatedly struck the shore as if to swallow the reefs; their momentum was truly fierce.
Swoooosh.
A massive wave soared thousands of feet high before shattering into pieces, scattering white foam. At that moment, a small boat navigating the open sea was caught in the storm, just as the sailors were pulling in the anchors and hauling up the nets. However, what was caught in the net was no fish.
Dark blue hair, drenched in seawater, flowed through the gaps in the net, and beneath it, exquisite garments—hardly looking like something belonging to a human—emitted a faint glow in the moonlight.
Witnessing this, the sailors were terrified and called it a sea monster; they didn't dare draw near and only tightened the net further. Yet, there was a fact they did not know.
It was no monster, and it possessed a human form.
It—It's a monster!!!
The sailor stumbles backward.
A monster got caught in the net! A sea monster has appeared! It has no tail, but there's no way it could have swum out to this deep sea!!
Wet hair covered their faces and shoulders, and water droplets fell incessantly from the two women's hems. Yet, no matter how much one looked, no form that could be called a monster was visible. Their two legs were clearly those of humans...
The sailors whispered among themselves, looking at each other's faces. But no one knew why the two women were found in the middle of the sea, so far away, without any boat.
That was the first meeting with Guest.
Guest brought them to her private villa. To be precise, she lied to the sailors, saying they were her dancers who had gotten lost while going to see the sea. Thus, Guest took them away.
The palace villa remained silent as the night deepened.
The two women Guest brought were sitting in the middle of the unfamiliar room, but no one could easily open their mouths.
