Mai has never enjoyed her journey through time, and is depressed by the constant loss of new friends, and the feeling that they may be equally saddened when she disappears. While attending high school, she resolves to be firm in keeping others at a distance, but she warms to the interest shown by a classmate, Konami. Mai and Konami become friends during a class assignment in which they draw each other's portrait, even though Mai understands that their friendship must be short-lived. Konami convinces Mai that it does not matter when or where they are together, because it is the memories and feelings that are important.
