The day the institute reclaimed him, he tore apart his control collar, blood on white scales, guns trained on him. Celia stepped between them: be good, Cy, I'll come get you soon. How long? he whispered. Just one day.

About the show

Source: SagaBox official drama page & player — editorial coverage based on the opening arc; series details verified 27 Oct 2026.

Episode one opens on the drive away from prison. Celia sits silent, staring out the window at a world she no longer recognizes. Tessa Arden, her former institute colleague, drives and talks a mile a minute — beastkins are in power now, the old Vera Institute is torn down, the old senior staff were all executed. Celia zones out and mumbles something about test subject 0207. She flashes back: the Vera Institute, a glass tank in the lab, a white-snake beastkin with silver hair and icy green eyes. She stopped his petri dish at the incinerator, insisted on adopting him for a year, named him Cyrus, taught him to read. He still had the mind of a child.

The flashback cuts to the day the institute reclaimed him. They noticed his power had surged. He tore apart his control collar, set off the shrill alarm, mangled the metal restraint over his mouth — blood soaking the white scales along his cheek. A whole team of security guards could not hold him. One of the higher-ups finally lost patience: can you get him back or not? if you can't, just kill him. Countless guns trained on Cyrus. Celia stepped forward, held him tight: be good, Cy, go with them for now, I'll come get you soon. His icy green eyes moved sluggishly, black pupils widening. How long? he whispered. Just one day.

Back in Tessa's downtown apartment, a two-story jellyfish aquarium dominates the living room. Tessa settles Celia in and makes coffee. You still have a thing for jellyfish? Celia asks. Tessa shrugs: I just keep them around to pass the time. She presses Celia to come work at her company. Celia looks at the jellyfish drifting behind the glass and says nothing. Seven years is a long time to be gone. And somewhere in the city above, the Beastkin Commander who once asked how long is already asking the same question again.

Meet the characters

Celia — The researcher released after seven years

Celia

Blonde, sharp-eyed, beige trench coat and white blouse. She developed the first white-snake beastkin test subject, saved him from disposal, and tamed him for one year before the institute forcibly reclaimed him. She is allowed to be quiet and shell-shocked, not instantly heroic.

Cyrus — Test subject 0207, now Beastkin Commander

Cyrus

Silver-haired, pale, icy green eyes that turn black when his power surges. Half-human, half white-snake beastkin. The day the institute took him, he tore apart his control collar; the last thing he said before sedation was how long? Now he commands the whole Beastkin army and has eyes only for the woman who promised one day.

Tessa — Celia's former colleague

Tessa

Blonde, polished, lives in a downtown apartment dominated by a two-story jellyfish aquarium. She picked Celia up from prison, offered her a place to stay, and pushed her to come work at her company — the woman who did well without her old colleague.

Standout beats

Episode 1 · The prison drive

Celia leaves prison and stares out the window at a world she no longer recognizes. Tessa talks nonstop about how everything changed. The camera lingers on Celia's face — she is not listening, she is hearing a number: 0207.

Episode 1 · The white-snake beastkin

Flashback to the Vera Institute. A glass tank, silver-haired young man with icy green eyes. Celia stops his petri dish at the incinerator. He still had the mind of a child; she named him Cyrus and taught him to read.

Episode 2 · The day they took him

Broken control collar, blood on white scales. The higher-up says if you can't get him back, just kill him. Celia steps between Cyrus and the guns: be good, Cy, I'll come get you soon. His question: how long? Her answer: just one day.

Episode 3 · The jellyfish apartment

Tessa's two-story jellyfish aquarium. She offers Celia a job, a couch, a future. Celia says nothing. The camera holds on the drifting jellyfish — and on the woman who promised one day and came back seven years late.

Editor's take

Our editors' notes on the opening arc — personal picks, not audience feedback.

WebDramas editorial · on the hook

The line just one day is spoken in episode two as a flashback, and the entire first episode is Celia walking back into a world that moved on without her. The beastkin setup is treated as a reunion, not a monster reveal.

WebDramas editorial · on Cyrus

He is written like a man who waited seven years, not a villain: the broken collar, the blood on the scales, the if you can't get him back line — all of it establishes his power is real and his love is older than the institute.

WebDramas editorial · on the atmosphere

Cold car-window gray in episode one, sterile lab blue in the flashback, warm apartment gold with drifting jellyfish in episode three. The show leans into the sci-fi reunion aesthetic without winking at it.

WebDramas editorial · the bottom line

Best for viewers who like atmospheric beastkin reunion romance with a possessive commander who waited seven years; if you need an instant meet-cute, this one opens on a prison release. Compared with most reunion shorts, the gap is seven years of worldbuilding rather than a misunderstanding — that weight is both its strength and its limit.
