Shade collecting / "pink obsession"
Many buyers explicitly say they can't buy just one shade and end up owning 3-8 tubes to complete the pink color range.
Sale and discount pricing
A large number of Japanese and other reviews mention buying because the product was on sale or unusually cheap for a popular fwee item.
Brand trust / repeat customer loyalty
Reviewers frequently state this is their 3rd, 4th, or 6th fwee lip tint purchase, citing consistent quality and 'always the best' formulas from the brand.
Word-of-mouth and salon/influencer recommendation
Some reviewers mention buying because a friend recommended it or because it was used at a makeup salon they visited.
Gifting
Several reviewers purchased multiples specifically as gifts for friends due to cute packaging and affordable price during sales.
