He knows

Feng Tian's heart raced in her chest as she stared at the man who was standing with his back turned to her, immediately, she blinked away the hot tears that were threatening to spill out and quickly push them down with a gulp as several questions began to run through her head. Sui An kidnapped her, does that mean he knew her identity? Did Wang Hai send him? 

'Feng Tian, calm down!' She chanted in her mind as she quickly clenched her hands, which were beginning to shake in a tight fist. Instantly, she whipped her head to the side to check the man beside her, but on hearing the loud echo of her slight movement, she inwardly muttered a curse.

On hearing the noise, Sui An smirked and gently dropped the cigarette he was holding to the floor before making his way towards her, his left foot crushing the cigarette in the process.
