Sweet Osmanthus Cookie

Sweet Osmanthus Cookie (Simplified Chinese: 四季桂饼干, sìjì guì bǐnggān, "Four Seasons Osmanthus Cookie"; Korean: 사계화맛 쿠키, sagyehwa-mat kuki, "Four Seasons Osmanthus Cookie") is an NPC who first appeared in the Perfumer's Quest update (v5.12).

She is a dutiful servant of the Osmanthus Mansion, and ensures the safety and whereabouts of Head Icon Red Osmanthus Cookie at all times... even if sometimes she loses track of her. Sweet Osmanthus Cookie's Appearing Cookies section of The Flower City reads as such:
Keeping Head Icon Red Osmanthus Cookie happy is what she does best!
She looks up to Head Icon Golden Osmanthus Cookie the most.
She's very shy, so she tends to be a wallflower at big events.
She tries her best to be her best self for Red Osmanthus Cookie.
She follows Red Osmanthus Cookie out late at night, but always loses her...
Both Sweet Osmanthus Cookie's original simplified Chinese name (四季桂饼干, sìjì guì bǐnggān) and original Korean name (사계화맛 쿠키, sagyehwa-mat kuki) translate to Four Seasons Osmanthus Cookie in English. "Sweet osmanthus" typically refers to the general species of osmanthus fragrans while "four seasons osmanthus" refers specifically to the semperflorens (Latin for "ever/always blooming") variety.
