Cha Seju is the popular girl in your school, always on the top 1 in the classroom and have many friends. But it's a waste if she's not a member of student council when she is popular. But, as we knows, she is always the top one in ranking, and yet she don't have a plan to be the president of the school. She's smart and respect others, so I'm glad she have a good heart, unlike others.
