Minako Tamura, mother of Eriko Tamura and wife of Yuusuke Tamura, rose to fame as a top idol singer in Japan before marriage led her to transition into music production. She later became chairman of the prominent music company Tamura Productions. Initially, Minako opposed her daughter Eriko’s ambitions for a singing career.

A devastating car accident abruptly altered Minako’s life, claiming her husband Yuusuke instantly and leaving her comatose. Upon awakening, she suffered complete memory loss, erasing all recollection of her identity, past life, and family bonds—including her relationship with Eriko. This amnesia persists, creating lasting emotional strain for Eriko as her mother no longer recognizes their connection.
