She wasn't unafraid of death.
She just didn't want to live anymore.
This life was just too lonely. After losing the vow to wait for that person, she found she couldn't find a reason to go on living.
No one loved her.
Lady Hyde was good to her, but she was Brandan's mother; at crucial moments, she would side with Brandan. William Moore was also good to her, but she didn't want to trouble him—he was her only true friend.
Sometimes she wondered if the reason she stubbornly waited for that person to return was simply because, in this world, he was the only one who loved her. That's why she was so desperate for Brandan to remember.
So when that hope was shattered, she lost the courage to live.
Because... it was truly too lonely.
Living alone was really too lonely.
