ATEEZ's official duo, Yeosang and Wooyoung, signaled a new beginning rather than an end to their 10-year friendship. In the ATEEZ year-end content "ANEWZ 2026 New Year's Edition" released on the 15th, the two looked back on their tight-knit bond since their trainee days and shared their unfiltered feelings for each other.

The highlight of the broadcast was the 10th-anniversary celebration session for Yeosang and Wooyoung, also known as 'Yeo-Woos.' Based on the deep trust built over a decade of sharing joys and sorrows, the two drew attention by making an extraordinary promise to stay together for the next 100 years.

"The friend who can't live without me" Wooyoung's declaration Wooyoung opened up first, expressing special affection for Yeosang by saying he believes he was able to make it this far with the other members because he could be with this friend.

In particular, Wooyoung defined Yeosang as a friend for whom it's hard to navigate this harsh world alone. He jokingly added a "guardian declaration," saying he would protect him well and plan to suffer together through the 30th, 50th, and even 100th anniversaries, causing laughter. Wooyoung's unique style of loyalty—implying that since they've suffered for 10 years, they might as well suffer for another 100—was on full display.

"Learning about the harsh world thanks to Wooyoung" Yeosang's counterattack Yeosang's response was equally sharp. He initially touched hearts by confessing that he wouldn't have been able to make it through the harsh world without the 10 years spent with Wooyoung.

However, Yeosang immediately countered by saying that Wooyoung makes the world so harsh that he is learning how to deal with it well in advance. Like true 10-year best friends, they dominated the atmosphere with a perfect "tiki-taka," alternating between touching moments and playful disses.

From trainee peers to 100-year partners The relationship between these two has moved beyond mere joking and has become the foundation of ATEEZ's teamwork. Their story, serving as each other's closest supporters from being trainee peers to becoming global artists, brought both great emotion and fun to ATINY (the fandom) worldwide.

The ATEEZ members sincerely congratulated the pair on their 10th anniversary, creating a warm atmosphere wishing them a "hundred-year union." As 2026 begins, all eyes are on the synergy the even more solidified Yeo-Woos friendship will showcase on stage.
