This manga centers on Kokoro, a teenage yuri fanatic who's dreading her impending arranged marriage. She seeks solace by escaping into the romantic fantasies she concocts for the pairs of women she and her friend observe while people-watching. The story has a cyclical rhythm of plot-advancing drama, Kokoro's charming daydreams, and vignettes of the subjects' real relationships (each of which are surprisingly interesting and could have been their own one-shots, if not series). The art could certainly be better on a technical level, but it more than makes up for it in creativity. It's absolutely full of interesting compositions and clever scene transitions. As of writing this,there are only two volumes officially published in English but I'm already hooked. Don't sleep on this hidden gem!
