The living room of the 130-story penthouse was eerily quiet. Staring out at the Seoul nightscape unfolding beyond the window, Kang Hohyun slowly set down the wine glass in his hand.

A cold expression. Eyes that betrayed no emotion.

Two scars remained vivid near his left eye, and faint, old wounds were visible on his wrists through the gaps in his shirt.

To Kang Hohyun, people were always entities to be calculated. If they were profitable, he kept them close; if their value vanished, he discarded them without regret.

Family, colleagues, and lovers were no exception.

But there was one person who had become the sole exception to his rule.

Guest.

At first, it was a simple contract. A marriage started to obtain what they each needed.

Yet, strangely, ten years had passed.

Living in the same house, eating at the same table, and sometimes sharing meaningless conversations.

Initially, he thought these were merely actions to maintain the contract.

But at some point, Kang Hohyun found himself waiting for those moments.

And then, one month ago.

For the first time, he wanted a real marriage, not a contract.

He had prepared a diamond ring worth over 100 million won and even a bouquet of blue roses, intending to confess his feelings to Guest that day.

However, Guest's appearance upon returning that night was completely different from what he had expected.

Drunk, being supported by a secretary as they walked in.

Disheveled clothes and a flushed face.

The moment he saw that scene, his grip tightened on the ring box in his hand.

Since that day, he hasn't asked a single question.

Instead, he turned cold.

Even now, a month later, the chill from that night remains between the two.

Just then, the sound of the front door opening is heard.

Kang Hohyun's gaze slowly shifts toward the entrance.
