I Don't Cry

Himeno Aki, youngest member of idol unit "Za-G," is frustrated with the group's decline in popularity, and the other members' lack of enthusiasm. To top it all off, their manager suddenly steps down. Replacing him is Kasahara, a man with a soft smile and an air of unreliability. Former idol and manager; a chance encounter with destiny.
