Repeat/loyal customer base
An unusually high share of reviewers mention buying their 2nd, 3rd, or even 10th+ bottle, some having used the product for 2+ years, indicating strong retention.
Sale/bundle pricing
Many buyers explicitly purchased during OliveYoung sale events or because the double-set with bonus mini treatment/conditioner was cheaper than buying single bottles or drugstore alternatives.
Scent variety and limited editions
New or limited-edition scents (Sakura, Rose Aura, Sweet Breeze, Tender Bloom) prompted purchases from existing fans wanting to try a different fragrance in the same formula.
Gifting
Several reviewers bought the set as a gift for mothers, sisters, or friends, citing the pleasant scent and packaging as gift-worthy.
Word-of-mouth and online hype
Buyers frequently cite reading positive reviews, seeing it recommended by friends, or being drawn in by online hype before trying it themselves.
