K-pop stars IU and RIIZE’s Anton have warmed hearts with their adorable online interaction, showcasing their long-standing friendship.

Following IU’s recent comeback, fans launched the “IStanU” challenge on social media, where participants express their love for the talented singer. Much to everyone’s surprise, Anton joined in the fun, posting his own rendition of the challenge on his group’s social media.

IU, clearly touched by Anton‘s gesture, reposted a screenshot of his challenge on her Instagram, showering him with praise and declaring, “He’s totally a pro…” She even went the extra mile to promote him, writing his name and group in the corner of the post.

This heartwarming exchange highlights the special bond between IU and Anton. Their connection goes beyond the idol industry, as IU is a close hoobae (junior) of Anton’s father, the renowned singer Yoon Sang.

Fans have been buzzing about their friendship for years, ever since Anton, prior to his debut, posted about a pair of Louis Vuitton shoes gifted to him by IU. He even mentioned a meal they shared together, and eagle-eyed fans noticed IU following his personal Instagram account even before he entered the spotlight.

With IU’s sweet gesture and Anton’s enthusiastic participation in the challenge, it’s clear that their friendship remains strong and continues to delight fans. This heartwarming display of camaraderie is sure to leave a lasting impression on the K-pop community.
