Mizuki plays a 35-year-old woman named Kurumi, who suddenly loses everything in her life when her fiance runs off with all of her assets. Left with a mere 15,000 yen and some boxes of ohagi (a type of rice ball), the despairing Kurumi happens upon a construction site, and she begins handing out the ohagi to the men working there. Using the theme of food, "Tenshi no Wakemae" depicts Kurumi's journey as she turns her life around.
