Yume Yorimitsu, 26, is an editor working in the editorial department of a gourmet magazine of a major publishing company. At first glance, she appears to be a loose-fitting girl like a sugar candy, in fact, she is a girl who drinks and has never met a man who drinks more than she does until she meets Kenjin Shiraho. A sweet-loving orakei man and a sake-drinking girl, in love with sweets in every corner of the world!
