SEOUL, April 13 — Actress and former After School member Nana has reportedly stood by her criticism of The Boyz’s Sunwoo, after a viral video of the idol sparked controversy over his behaviour toward a security guard.

According to a report in The Korea Times, the footage, which circulated widely on social media, was said to show Sunwoo dropping his wireless earbuds and remaining still as a security guard picked them up and returned them using both hands.
