Saori’s greatest anxiety was her relationship with her friends.
After coming back to herself , Saori wanted to send e-mail to her friends but the cellular phone was banned in the hospital.
One of her friends was a boy, whose name was Mizuki. He was a graduate student of T Technology university. She was introduced him by a friend. Once she met him at a coffee shop in Tokyo with her friend. Around the time when she did not yet judge whether she would keep in contact with him or not, she attempted suicide on a sudden impulse.
Then she could not help coming back home to Akita.
Instead of Kyoko, her elder sister routinely visited Saori in the hospital. However, in spite of her aunt’s kindness, Saori found it difficult to ask her aunt to do something for her. In particular, it was about a cellular phone, sending e-mail to her friends.
