Touka knew she loved Kaneki. She knew that she was prepared to die for him. She knew he was stronger than her; but strong people needed help too. Touka knew she was in love with Kaneki - but she didn't want to jeopardise his mission with Aogiri. She didn't want to be the reason he failed. He came to her rescue; over and over and over again. He'd give up anything to rescue her.
