Ferdinand was listening to the mellow music as he reminiscence his time with Anastasia during their honeymoon stage. They would prepare dinner together and dance after the song "I'll make love to you" by the Boyz II Men. Classic and whenever he sings it and reach the chorus—she would flush and mutter something to him that would make him hot.
He smiles as he remember. It was so real in his head, the fantasy he feels right as he reminiscence that he was still young and love it whenever he carries her everyday to their bed. He had love her dearly and even though he didn't say it everyday, they both know that what they feel is true and no one can break them apart.
Whenever he sees Catriona and Enzo, he feel bad for himself to loose his wife too early. He could see and compare himself with Enzo back then, taking care of the triplets and making sure that they didn't get any rashes and assisting the wife. He left the mansion in order to give them some privacy. He's old and lonely.
