Damien closed the journal and put it inside the drawer of his bedside table. As Suzanne mentioned to him, Oliver Barnard had put every incident of his life in the journal and Prince Philip's incident was also mentioned in that.
He sat on the chair by the window and clasped his fingers together. He was shocked to find out a few things about his father too. Philip wanted to marry Anneliese. Oliver mentioned how Philip had a huge fight with Christian over Anneliese and with that, they started growing apart.
Damien wondered if his father never loved his mother. That particular incident that Philip shared with Oliver shook Damien inside out. Philip loved a woman more than his mother, who was Édouard's mother. Any child would be devastated to find out that.
However, as he proceeded to read more, he found out Oliver mentioned how happily Christian and Philip shared the news of becoming a father to him. It only meant that Philip had moved on after some time.
