Luke had invited Isabella to have lunch with him at a restaurant, inviting Claire as well but Isabella had refused. She didn't want to be with Luke when Claire was around, and that was why she didn't go with him.
When he came back, Luke went straight to her room to see that she had her bag ready to leave with him.
He watched her from the door, having nothing on his mind, just staring at her, and until she realized he was behind her, he didn't aim to approach her.
"You were staring," she confronted him.
"I couldn't stop staring," he said. "I was captured by your beauty and sexiness," he licked his lower lip.
"What about Claire?"
"I told you she was going back home," he answered.
"Why isn't she married?"
"She got divorced," he explained.
"I hate divorce," she frowned. But Luke didn't reply, he was just lost, staring at her.
"What are you thinking?" She pushed him by his shoulder.
