Influencer/idol recommendation
Many reviewers (Japanese, Korean, and English) mention buying after seeing a specific influencer, YouTuber, or idol wearing the shade, indicating strong social-media-driven demand.
Packaging appeal (pacage-buy)
A large share of reviews, especially in Japanese ('パケ買い'), state they bought primarily for the cute glass bottle design rather than the formula itself.
Shade/color collecting
Multiple reviewers say they are 'collecting' or plan to buy 'all the shades,' suggesting the multi-color lineup drives repeat and multi-SKU purchases.
Repurchase/loyalty
Several reviewers explicitly state this is their 2nd or repeat purchase and that they will 'always buy' the line, showing brand loyalty despite known longevity issues.
Ingredient/hydration reputation
Reviewers frequently cite the moisturizing, non-drying formula as a reason for choosing this over other tints, especially for dry-lipped users.
