Kazuhiko Nukumizu is used to being invisible at school, which is exactly how he ends up witnessing something nobody else does: Anna Yanami, one of the most popular girls in class, getting flatly rejected by the childhood friend she's liked for years. Anna isn't the only 'losing heroine' nursing a fresh rejection, though. Chika Komari and Lemon Yakishio are dealing with their own, and Nukumizu, without ever volunteering for the job, becomes the one person all three end up talking to. This manga adapts the same story as its light-novel source.
