By marrying her, Tony Takitani brought the lonely period of his life to an end.
When he awoke in the morning, the first thing he did was look for her. When he found her sleeping next to him, he felt relief. When she wasn't there, he
felt anxious and searched the house for her. There was something odd for
him about not feeling lonely. The very fact that he had ceased to be lonely
caused him to fear the possibility of becoming lonely again.
