From Day One, happy-go-lucky Yuzu makes enemies, namely the beautiful yet stern Student Council President Mei. So what happens when a dejected Yuzu returns home and discovers the shock of her life: that Mei is actually her new step-sister who has come to live with her? Even more surprising, when Mei catches Yuzu off-guard and kisses her out of the blue, what does it all mean?
