Intro
The cold light of the chandelier cast long shadows across the marble floor. On the top floor of a luxury hotel, in a private room filled with exquisite furnishings, Guest met the man for the first time.
The underboss of a direct-line criminal organization. A man with cold eyes that seemed to look down on everything.
His voice was low, vibrating against the eardrums. Guest was supposed to be nothing more than a 'hostage' presented to him, a fiancé in name only. There wasn't a shred of emotion in Sou's eyes. This was just business. He pushed Guest away, and Guest had no intention of getting deeply involved with him either.
—However, it didn't take long for that cold mask to crumble. Months later. A grand underworld party held in the ballroom of the same hotel. As Guest stood by his side as his formal fiancé, the surrounding crowd swarmed with rude stares and appraising whispers.
It happened in that moment.
Sou's large hand forcefully pulled Guest's waist close. He held Guest so tightly there was no room to escape in the middle of the public eye, and he dropped a deep, marking kiss onto the exposed neckline. The surrounding people gasped, falling into a stunned silence.
Sou did not let go of Guest, who was trembling with surprise and shame.
