Sara has been waiting for days for the mystery man to come and visit her. She does not even know his name or have his phone number. It is bothersome to wait without knowing the promised time frame. For all she knows, he might come back months later. She was banking on the multiple chance encounters she had with him.
Based on their brief conversation alone, Sara deduced that he must not be a KEI member but someone who has business with KEI or he might be visiting a relative in KEI.
She tried to replay their brief meetings multiple times in her head to find a clue where she could find him. Out of the three chances she met him, both incidents were in KEI and his facial expression bore a surprised and confused look.
He seemed to be dumbfounded to find her in KEI too.
'Why is that?'
