Influencer/idol association
Multiple reviewers explicitly say they bought a shade because IVE's Wonyoung wore it or it was her 'pick,' driving trial of specific colors like Seoul Girl.
Brand loyalty and repurchase
Many reviewers note this is their 2nd-5th tube of the Jel-Fit line or of Amuse products generally, citing consistent quality across purchases.
Sale/discount pricing
A large number of Japanese and other reviews mention buying because the product was heavily discounted or bundled in a set, calling it a great deal.
Wide, flattering shade range
Reviewers frequently mention choosing this tint because the 11-shade lineup includes options for both warm (yellow) and cool (blue) undertones, deep and light skin tones.
Gifting
Several reviews state the tint was purchased as a gift, citing cute packaging and universally flattering color as reasons it's a popular present.
