Christian looked at the beautiful woman in front of him and observed how she held a conversation with Marc and Johnny. To others Isobel seemed close to perfect, she was beautiful to look at, smart, educated, kind— and Christian could not disagree with that.
In the past, Francesca had always been outspoken over how perfect Isobel would be for Christian while the two at the time got embarrassed by her statements. It had not only been Francesca but a huge majority who had shared those same thoughts, but for Christian that was a no-go.
He did not like her in that way and ignored the crush she had developed, but he had no problem whatsoever with how she threw himself on him and took advantage of her. Despite throwing several hints that he was not looking for a relationship, she still came back to him, hoping he would eventually change his mind.
