Free Soul and Yellow Book are two thoughtful and understated josei/seinen slice-of-life manga with very sparse linework. Both are about the relationship a person has with a character in a novel (how the fictional character affects them, etc.)
Monokuro Kinderbook and The Yellow Book are two series of vignettes that glimpse into the ordinary abnormal day of the average woman. All sorts of topics are explored, from falling in love with characters from classical French literature to buying skimpy underwear because of a something a fortune-teller said. All sorts of women are focused on- highschoolers, the elderly, and everyone in-between. Both are extremely understated, and most stories lack a finite beginning or end.
