The innocent, talkative, cute, and overachieving freshman freshman girl Ku Sa, a master of games, all-around sports, and open-minded sophomore senior is a tall, doting sister, all-around athlete, and a bit of a straight boy who helps his best brother sign in, earns credits, and takes good care of his good brother when he is sick. The third-year senior is a good brother who is a warm-hearted man, but also has a double standard. Book title: "Freshman Schoolgirl, Sophomore Schoolgirl"
