Two months after IVE wrapped up their 'IVE SWITCH' era, the group's hit track 'Attitude' is still climbing charts and dominating short-form platforms—and Rei's viral "Guinea Pig" part is leading the charge.
💥 Rei's "Guinea Pig Part" Takes Over TikTok
IVE's Rei became the face of a fan-made viral moment, dubbed the "폭주기니" ("Raging Guinea Pig") part of Attitude. In the clip, Rei flashes her signature eye-smile while powerfully swinging her arms—a move that wasn't even part of the song's main chorus.
Fans named the part themselves and turned it into a challenge. IVE later jumped on the trend, posting their own versions.
🌍 38.6 Million Views and Counting
Rei's TikTok challenge clips recorded 26.5M and 12.1M views, respectively, as of April 9—racking up a combined 38.6 million views. The challenge took off across platforms like TikTok, Instagram Reels, and YouTube Shorts.
From global fans to fellow K-pop stars, everyone joined in. Participating artists included:
- Red Velvet
- LE SSERAFIM
- ZEROBASEONE
- MONSTA X
- NCT WISH
- BOYNEXTDOOR
- TWS
- STAYC
- CRAVITY

- Lee Young-ji, and more.
Even animated characters like TiniPing, Jjanggu Lupee, and Bellygom took part, making it a hit among young fans too.
🎤 Encore Moments & Trend-Setter Status
During an encore stage on Inkigayo, IVE surprised fans by singing "Guinea Pig" in the lyrics. Rei's adorable energy and steady vocals charmed fans once again.
Beyond "Guinea Pig," Rei has also launched other trends such as:

She continues to shine at official events and in personal content.
📈 Chart & Sales Domination

- The group maintained strong showings on Global 200, Billboard Japan Hot 100, and Oricon.
The album recorded 1.04 million copies in first-week sales, becoming the highest 2025 first-week seller so far and earning IVE their 5th consecutive million-seller.
IVE also swept 15 Korean music show wins, picking up trophies even after promotions ended.
