aespa Winter's fandom launched an extraordinary series of ads to celebrate the idol's birthday on New Year's Day.

On an online forum, netizens shared their impressions after spotting Winter's birthday ads across Seoul. These ads appeared on billboards at subway stations, buildings, bus stops, and more, showcasing the remarkable dedication of Winter's "core fandom" as a member of aespa. The sheer number of ads left many netizens pleasantly surprised, reflecting Winter’s growing popularity and influence.

The ads were also displayed on screens in every Olive Young store throughout South Korea.

Born on January 1, 2001, Winter is renowned for her unique birthday, being a true 'winter baby.'

One forum poster detailed the scale of the celebration:

"Winter's Chinese fan club organized a birthday event on a massive scale, putting up birthday advertisements all over Seoul, including streets, buildings, subways, and bus stops. It’s so extensive that it seems like everyone living in Seoul would know it's Winter’s birthday.

Since only 12 photos can be attached at a time, many couldn’t be included, but there are even more than what’s shown in the main post. Beyond this, Winter's birthday ads were placed in every Olive Young store nationwide. They also ran a shuttle bus decorated with birthday messages and photos near the SM Entertainment building, rented a subway train on Line 2 that was covered with Winter’s pictures and congratulatory messages, and even purchased land in Seoul Forest to create a dedicated 'Winter Forest' space.

Among 4th-generation female idols, it seems Winter's birthday event is on an overwhelmingly large scale."

Netizens took to the forum to congratulate Winter and share their thoughts:

"Happy birthday, Winter~~ January 1st is such a unique birthday, lol."

"She’s even born in 2001, so her birthday is 010101, lol."

"Winter's birthday ads displayed in Olive Young stores nationwide."

"Winter was truly born in winter~~"

"I’m not even a fan, but Winter really has the vibe of a winter fairy with her voice and visuals. Happy birthday!"

"Winter's core is amazing. Happy birthday!"

"She’s really popular."

"Wow, that’s incredible. Were the ads only in Seoul? I wish I could’ve seen just one in person."

"Don’t most top-tier idols do this kind of thing?"

"It’s such a shame that the birthday ads weren’t broadcast during the Gayo Daejejeon. Hopefully, they’ll do it next year."

"That's a birthday bus operating near the Seongsu-dong SM building."
