Kaori Fujimiya

Following a traffic accident, Kaori was left with a rare condition that erases all memories of her friends every Monday. To shield those around her from the pain of her repeated forgetting, she initially withdrew into solitude, keeping everyone at arm's length. Everything changed when her classmate Yuki Hase refused to give up on her. Encouraged by his unwavering presence, Kaori began keeping a diary to preserve the moments she would otherwise lose. Despite the relentless cycle of memory resets, she finds the courage each week to rebuild meaningful bonds with the people who matter most to her.
