Mitsuki Shirasaka

A hospital patient grappling with amnesia, this character's past is shrouded in mystery. A past shared with her younger sister, Shiho, involved running a flower shop that ended tragically due to Mitsuki's severe anaphylactic reaction. This traumatic event, coupled with her deep love for flowers, led to profound depression and the loss of her memories, making it impossible for her to recognize her sister.
