AtHeart takes on 99-Second Standby~ Cue! and Random Play Dance... 'Energy' choreography to win hearts

The group AtHeart showed their struggle to earn hearts through missions. In the 'IDOL 1N2D' EP.75 video released on the KBS Kpop channel on September 20, 2026, the process of AtHeart members collecting hearts to save a gift trapped by magic was captured.

99-Second Standby~ Cue! Relay Mission, AtHeart succeeds on the second attempt

As the first mission to save the gift, AtHeart challenged '99-Second Standby~ Cue!'. In this mission, where six missions must be performed in a relay within 99 seconds, if even one person fails, they must start over from the beginning, and a rule was applied where held hearts are deducted upon failure. The mission composition was set as peeling a boiled eggshell with one hand, eating a lemon and whistling, spinning a pressure point flower, blowing bubblegum, reading a sentence without mistakes, and jumping to a specific location.

In the first attempt, the members failed as they exceeded the time while performing the missions. In particular, during the process of peeling the eggshell with one hand, situations occurred where the egg was broken or time was delayed. The members decided to retry, and in the second attempt, through the members' efforts, they achieved success by completing all missions within 99 seconds.

Winning with 'Energy' even without knowing the choreography, Random Play Dance mission

The second mission was 'Random Play Dance', where three or more members must complete the choreography to music played randomly. AtHeart members showed their determination to compete with 'energy' even if they had not perfectly mastered the choreography. The members expressed their intention to challenge by saying, "Even if we don't know the choreography, we will look at the energy score," and "20% of the choreography is the moves and 80% is the energy."

While the mission was in progress, the members showcased choreography to various songs. In some songs, situations occurred where they could not perform the choreography accurately, but the members did not give up and continued the movements. In particular, unexpected appearances occurred, such as one member performing a movement as if making ice cream. Through this process, AtHeart continued their mission success and earned hearts.

Comeback and anniversary celebration, meeting at Seoul Metropolitan Government's Eoullim Plaza

This video was filmed at 'Eoullim Plaza', Korea's first barrier-free welfare-culture complex space. AtHeart shared the news of their recent comeback remaking Roo'ra's song 'Sneaker', stating that they reinterpreted this song by capturing the group's unique refreshing feeling and energy.

Additionally, to celebrate the group's 1st anniversary and member SEOHYUN's birthday on August 13, the members had a time of celebration while checking the gift prepared by the 'IDOL 1N2D' side. The members added variety-show fun by challenging a gift draw using the hearts earned through the missions.
