TWICE held a special fansign event on June 12 at Starfield Coex Mall hosted by one of their major endorsements, Pocari Sweat. As if seeing 9 beautiful idols weren't enough, ONCEs were in for a treat because among them attending the event was IZ*ONE's Yabuki Nako.

Nako has always been known both to TWICE and IZ*ONE fans as a self-confessed TWICE fanatic. In fact, prior to IZ*ONE's debut, she has been vocal about supporting her favorite girl group. She was even seen showing off her copy of TWICE's Japanese album. 

The adorable Japanese idol has been caught in numerous occasions fangirling over TWICE. One of which was during IZ*ONE's fansign event when she happily held a laburi doll and a magazine with TWICE on the cover. She has also been filmed several times proudly dancing to TWICE's songs.
