Nora no Inochi

Raku Hirano, a 25-year-old freeter working at a local Thai restaurant, is known as Nora by those around her. After her shifts, she hangs out with friends until morning, and sometimes has physical relationships with strangers... She has no savings, no place to live (she's freeloading at a friend's house), and no idea what the future holds. But she actually quite likes her carefree life. One day, however, Nora's every day life—no, her entire life—is shaken to its core!?
