Life was supposed to change for the better.

After reincarnating as a tiny, adorable angel—complete with halo and wings—she decides to make the most of it. Streaming, going viral, maybe even living an easy life powered by divine charm…

Instead, she gets captured.

Dragged into the Korean branch of a secret Anomaly Management Agency, she’s locked away inside a containment facility in Chungju—labeled, observed, and treated as just another “entity.”

Unfair.

But life in captivity isn’t quite what she expected.

Between daily tests and quiet negotiations, she befriends a kind researcher, Han A-young, purifies a possessed Jindo dog into a loyal companion, and even strikes a bizarre deal with a rampaging soccer ball anomaly.

Surrounded by strange creatures and even stranger people, her new life becomes… unexpectedly comfortable.

At least, on the surface.

Because within the facility, not everything can be contained.

Some anomalies whisper from the dark.
Some never leave once you see them.
And some… are quietly waiting.

A cute angel. A hidden power. A world of anomalies.

And a “beloved specimen” the agency refuses to let go.
