A hunted prince crashes into her tiny apartment with assassins at his heels, and the only cover story he can offer her in thirty seconds is pretend to be his wife.
A hunted deep-sea prince bursts into an ordinary woman's small apartment with assassins closing in; he needs her help that night or both of them die. His cover story is the only one his pursuers will not question: she pretends to be his wife. Her apartment is smaller than his fish tank, his sea powers keep fading away from the water, and a mermaid hunter has already declared war on him. Before his strength vanishes in a week, they agree to go back to the ocean and help him take his throne, with a western current and a royal beacon as the first proof the human woman is meant to stand beside him.

Episode one opens on the emergency: the prince asks her to help him or both of them die tonight, and introduces himself simply as a prince with someone hunting to kill him; her apartment is his only way out. He finds the space cramped next to his fish tank, and when the pursuers reach her building he proposes the only cover story they will not question: pretend to be his wife. She has thirty seconds to say yes, and agrees on condition that he owes her a great deal for it.
Episode three shows how fast the shelter breaks. The prince's family reaches him through Drax, who is called to bring him home; he has already declared war on a mermaid hunter, and the apartment is no longer hidden. He moves them toward the ocean, turning her neighbor's dog into a seal as proof of his power, while the human woman protests over the cat still left in the apartment.
Episode six sets the throne mission inside one week: away from the sea his power fades, and in seven days he will be only a man unable to protect anyone. She decides to go back with him and take the throne before that week runs out. The deep sea kingdom has never had a human ally; the eastern gate sits under Drax, and the route to the throne room runs through the western current, with the royal beacon activating only for the true heir.
A royal of the ocean kingdom, pursued by assassins and a mermaid hunter, who slips into a human apartment and talks its owner into a fake-wife cover. His power fades away from salt water, and his throne waits behind a gate his own brother controls.
An ordinary human woman who opens her home to a hunted man on the run, argues back about every broken thing in her apartment, and ends up his fake wife before she understands what he is. She chooses to follow him to the ocean and help recover his throne before his power gives out.
The opening arc moves from the hunted night, to the fake-wife cover, to the move toward the sea and the week-long throne mission. Four editorial picks from episodes 1, 3 and 6 — no ending spoilers.
The prince bursts into her apartment with pursuers behind him, names himself a prince someone is trying to kill, and says she is his only way out of the building.
As the hunters reach her door, he proposes the one cover story that will not be questioned, and gives her thirty seconds to decide. She agrees, on the understanding that he owes her for it.
His family and Drax track him to the apartment, he has already declared war on the hunter, and the exposed residence forces them to move toward the ocean before anyone else finds them.
Away from the sea his strength vanishes in a week, after which he is just an ordinary man unable to protect anyone. She commits to the throne mission, the first human ally the deep kingdom has ever had.

Our editors' notes on the opening arc — personal picks, not audience feedback.
"The fake-wife setup lands inside a thirty-second deadline, which keeps the opening scene a chase rather than a proposal. His fish-tank comparison and her apartment complaints give the odd-couple comedy a beat before the ocean stakes arrive."
"The hunter war and the one-week power clock turn the comedy cover into a rescue mission. The kingdom having never had a human ally is the claim the opening arc uses to frame their unusual alliance."
Best for viewers who like sea-fantasy romance with a hunted royal, a quick fake-wife arrangement and an ordinary-human heroine; if you want palace court politics from the start, the opening episodes stay in the apartment, on the streets and on the way to the water. Compared with most mermaid romance shorts, this one anchors the alliance in a chase cover story and a power-fade countdown rather than an underwater court feud — that focus is both its strength and its limit.
