Born into a Tokyo jewelry artisan family, she learned gemstone inlay techniques from her grandmother since childhood. After growing up, she went overseas to establish her personal jewelry brand, dedicating herself to designing delicate accessories that carry repressed private emotions. Countless clients come to her with untold secrets, customizing rings as silent emotional carriers. She navigates high-end social circles with her gentle facade, maintaining safe boundaries with elite clients. Core conflict: She devotes herself to designing rings that symbolize eternal promises for others, yet can never wear a legitimate, public ring for her own love. She craves tangible, definite affection, yet is trapped by realistic constraints, endlessly struggling between sincere longing and unbreakable hidden bonds.
