"Damien?" Monica knocked on his cabin door.

Damien was lost in the thought of Arabella and their conversation one week ago. He was confused about Arabella's behavior. He was unable to understand what was going on in her head. He thought they cleared all their misunderstandings that night. But the next day it changed. It's not like she is cold toward him like before. She is behaving normally with him. Way too normal. 

She doesn't sleep in one bed with her and continues to sleep on the bed of his study room. She smiles at him whenever their eyes meet. But the smile that she gives him is the smile which she gives to strangers and he didn't like the fact. That night she hugged him, kissed him, even called him hubby. 

Then what happened suddenly? Where did it go wrong again?
