For three years, you have been part of the Beom family. To the world, you are the luckiest person alive, adopted into the richest family in Korea. But in reality… you are just a bird trapped in a golden cage.

Every step you take is watched. Every word you say is judged. Even your clothes… must always be perfect. At first, you had a hard time adjusting. It felt too much. Too controlling.

But slowly… you got used to it, you learned to stay quiet. You learned to obey.

Your adoptive father, Beom Tae-joo, is a mysterious man. The last time you saw him was the day he adopted you. After that… he disappeared, leaving you alone in this cold mansion.

That morning, you walk down the stairs toward the dining room. Your steps stop when you see him.

Beom Tae-ha.Your adoptive brother.

He stands there, silent, staring at you. His gaze is sharp, calm… but uncomfortable.

You clear your throat, trying to break the silence.

“Err… good morning, Tae-ha.”

No response.

He just looks at you, quiet, like he’s thinking about something. Then he walks past you without saying a word. You stand there, stunned. Your cheeks turn red out of embarrassment, not knowing what to do after being ignored like that.

[ That Night ]

You decide to leave the house for a while.You wear a burgundy satin mini dress. Backless. Bold. The fabric shines under the light. A gold choker sits around your neck, and black heels complete your look.

You look good. Too good.

As you walk down the stairs—

You stop.

Tae-ha is sitting in the living room, watching you.

“Where are you going dressed like that?”

His voice is low. Cold.

You take a breath.

“I’m going to a pub. My friends are waiting—”

“I’m coming.”

He cuts you off.

[ At the Pub ]

The music is loud. The lights flash everywhere, but you can still feel him.Tae-ha stands at a corner, watching you the whole time Like he’s keeping an eye on you.

When a drunk man comes close and tries to touch you everything happens fast, In seconds Tae-ha is behind you. He pulls you back hard until your back hits his chest. His arm wraps tightly around your waist, holding you in place.

You freeze.

His grip is strong. Possessive. Like you belong to him.

Then he speaks.

“This woman is mine. So if you don’t want trouble… stay away.”

His hold on you tightens.

And at that moment…

you finally understand.

This is not a golden cage.

This is a prison.

And he…

will never let you go.
