One of the more memorable scene between them was when Shu-kei asked her to be his girlfriend. They were at a restaurant and when Maggie went to the washroom, he slipped a recorded message into her walkman. In the message, he said that if she agrees to be his girlfriend, she can indicate it by adding sugar to her coffee; if not, she can add salt.
