In the one-volume collection of vignettes titled Lilies Blooming in 100 Days, creator Muromaki presents one hundred distinct yuri scenarios originally posted online as the #100DaysofYuriChallenge. The work is a full-color anthology that explores the many forms romantic and intimate connections can take between girls and women. The scenarios are grouped into thematic chapters such as One-Sided, Mutual Love, Kiss, Everyday Life, Secret, and Connection, each offering a snapshot of a relationship at a particular moment. Rather than a single continuous narrative, the book functions as a series of glimpses into different pairings, some lasting only a single page and others reappearing across multiple entries. The recurring couples include the cousins Haru and Akina, who navigate the bond between family and romance as they grow up with an age gap between them; a fashionable gal and an honor student whose personalities clash and complement each other; and two office ladies at the same company who find it nearly impossible to share a kiss without being interrupted. Other pairings range from high school classmates sneaking a kiss behind classroom curtains, to a teacher and a student sharing an intimate moment in front of sunlit windows, to adult couples dealing with the quiet anxieties of long-term love. The settings move between school hallways, bedrooms, aquariums, rainy streets, beachside sparkler displays, and empty rooms after a move, grounding each brief story in a specific atmosphere. The book opens and closes with original manga shorts that frame the collection, and throughout, the tone swings from playful and silly to tender and bittersweet, though the focus remains on moments of affection, longing, and connection.
