Sato Reiko (Aoi Yu) is an ordinary girl with no skills. She has just graduated from college and lives with her parents. She is at a loss for the future. She is introverted and stubborn by nature. She often conflicts with her family. Finally, she decided to work and save one million to move out and find her own life. Reiko did not break her promise. After saving one million, she left home with a suitcase and began to travel around. When she arrived at the beach, she sold smoothies in a small shop; when she arrived in the mountains, she helped fruit farmers pick peaches. Working everywhere allowed her to save one million one after another. Every time she saved enough, she set off for the next place. It was easy to save money, but she didn't know where the life she wanted was. However, in the process of frequently changing places to work, Reiko was also learning to get along with others. From the initial embarrassment, panic and vigilance, to being able to make friends, when she worked in a flower shop, she met Nakajima (Mirai Moriyama), a college student who kept borrowing money from her. The confusion and search for a long time seemed to have answers...
