Aya dreams of living in Tokyo. As a high school student, she visits Harajuku. She realizes that in Tokyo, no one takes notice of her beauty. Years later, she finally moves to Tokyo to start her new life. Her first home is in Sangenjaya. People at her new job, a clothing company, spend time and money enjoying their private life. Aya thinks about what kind of woman she should be in such a workplace.

Aya meets Naoki, who has a sweet yet simple smile -- just like the Sangenjaya district. They gradually become attracted to each other. She is getting comfortable at her job. Her coworkers often go to dating parties, and Ryoko, an experienced dater, dislikes Yuki for dating as often as her. Keisuke and Aya witness their fierce battle, and Naoki is anxious about Yuki's promiscuity.

Aya is almost 30. Her coworkers are starting to consider switching jobs for better careers. Aya no longer sees Takayuki, and her boss tells her that she has already peaked at her job. She decides to look for career advancement and has an interview with a high-end brand company. She leaves Ebisu for a new chapter in life.
