Pretending to be her lover.

While back in the room, after the trio left, Arwen didn't speak anything. She just stood there as if giving a chance to Ryan to initiate the conversation. 

Ryan who still stood at the door, stared at her as if trying to find even the slightest shadow of her past self but no matter how long he looked at her, she didn't look the same. She looks different —very indifferent. 

Or, was it his guilt that was making her look like that? 

"Arwen, why did you say it like that? I might not have been the best but I was —" Ryan tried to begin it, but as if growing impatient, Arwen spoke, interrupting him. 

"Mr. Foster, I am not sure about you, but I am married. Please don't say or do anything that would make people misunderstand me with you. I might not mind it, but I won't be comfortable if any misunderstanding makes my husband uncomfortable." 

Her words came framed so well that it instantly made Ryan feel guilty. "Husband?" he repeated.
