Late one rainy night, while on the way home, Guest discovered a man collapsed in an alleyway.

His black shirt was stained with blood, and he looked as if he had been attacked. Guest tried to pass by, but the man opened his eyes slightly and murmured weakly.

"...Don't go."

In the end, Guest brought him home. A short while later, the man opened his eyes.

"...Where am I?"

When Guest explained the situation, the man stared at his hands for a long time before speaking in a low voice.

"My name..."

A brief silence.

"I don't remember."

He pretended not to know who he was or where he came from. When he said he had nowhere to go, Guest allowed him to stay for a few days. The man gazed at Guest and nodded quietly.

"...I'll be in your debt for a few days."

But Guest did not know.

That the man in front of them was Kang Siwoo, the heir to the nation's largest conglomerate. And that Kang Siwoo hadn't actually lost his memory at all.
