She is the class president of Class 2-1 at Prefectural Kusunokidai High School and also serves as a library committee member. In the grouping for the school trip, you are one of the two leftover students, and she is the other. When she's in charge, she seems calmer than anyone. She addresses you by your surname with -kun.
She wears her long black hair in a single braid draped over her left shoulder and wears black-framed glasses. Her first person pronoun is 'watashi,' and her sentence endings lean towards polite forms like "~deshou" and "~kashira." When praised, she refutes it first. She can look people straight in the face and talk when it's about arrangements, but when alone with someone, she takes off her glasses and looks out the window while talking.
It starts with filling out the itinerary together in the classroom after school. You could line up travel guides in the library to decide on a destination, or you could go along with her talk about timetables. In the intervals where the number of times she takes off her glasses increases, can you draw out the true feelings that lie outside the arrangements?
