Hachi tells herself that she's got her eye on the future and her life with Takumi, but she just can't let go of the past and her friendship with Nana and the rest of Blast--especially Nobu. And the tangle gets thicker when Hachi's wedding has to be postponed in favor of Nana and Ren's nuptials. Can Hachi handle another delay in her happily-ever-after?
