Nana, a former member of After School and an actress, faced criticism from fans of The Boyz’s Sunwoo after she commented on his behavior in a video that went viral, sparking a significant online controversy.

The video depicted Sunwoo dropping his AirPods as he walked towards an elevator. Upon realizing this, he shouted for them and a security guard promptly picked them up and handed them to him. However, Sunwoo received the AirPods with one hand without expressing gratitude, leading to backlash online. Netizens accused him of not picking up the AirPods himself, shouting for them, and lacking proper appreciation for the security guard's assistance.

Nana's response to the incident, where she criticized Sunwoo's actions and said he needed to be scolded, fueled further debate and drew strong reactions from fans of The Boyz, who expressed their discontent on Instagram.

In response, fans flooded Nana's Instagram with angry comments, some demanding an apology for Sunwoo, and others questioning her focus on this issue instead of addressing concerns about other celebrities. Despite the backlash, Sunwoo eventually addressed the controversy through a fan platform, admitting that the video made it appear as though he lacked manners.

He clarified that he was confused at the moment when a fan shouted, only realizing later that his AirPods had fallen. While admitting his actions may have seemed rude, Sunwoo apologized and pledged to show better behavior in the future to avoid misunderstandings.

The fallout from the incident continues as fans express disappointment and divided opinions on social media, with some defending Sunwoo while others support Nana's criticism of his behavior. This controversy highlights how seemingly minor incidents can quickly escalate in the K-pop industry, with fan reactions shaping the narrative and impacting the reputations of those involved.
