Volume 1 synopsis: [Includes digital-exclusive bonus paper] My (emotional) life expectancy is one year! Before it runs out, I will complete it… the ultimate "Yuri Sketchbook"! Kokoro has an arranged political marriage waiting for her the moment she graduates high school. To her, such a marriage is no different from death. To soothe herself in the afterlife, she throws herself into fantasizing about every form of yuri imaginable… This is the story of a girl doing her best for the girls she loves....
This manga is about a girl who will be forcibly married off after graduating high school, so she decides to spend her time until then fantasizing about imagined yuri relationships. It's an interesting idea in theory, but the manga has several problems.
First, the format is really jarring. Every chapter is broken into two parts. The first follows the main character and her friend finding a random pair of girls to fantasize about. Then the second part shows you what the pair of girls are actually like together. This sounds fine in theory, but it means half the time you're reading about one-off characters, leaving little time to develop the main character. And really it's even worse than that since some pages in the first part are about the main character's imagination.
Second, the art is pretty bad. I suppose if 90s and early 2000s shoujo manga art style is your favorite thing ever then you'll love it. Personally, I'm not a fan of the art style in general, but I really can't take it seriously in a manga that started publication in 2019.
For full disclosure, I only finished half the first volume before dropping it. I flipped through the rest of the first volume and a bit of the second to see if it might get better, but nothing I saw gave me any reason to think it would.
