Park Seo Joon became embroiled in an attitude controversy during the stage greeting for his new film 'Concrete Utopia'.

Recently, one exclusive media outlet reported on an anonymous netizen's post involving Park Seo Joon which received a lot of attention. This particular post criticized Park Seo Joon for his atitude during the stage greeting event of his new film 'Concrete Utopia'. According to the netizen, one fan who attended the event had prepared couple headbands for Park Seo Joon and Park Bo Young, who played a couple in the film. Park Bo Young received the headbands and handed one to Park Seo Joon, while wearing one herself. However, Park Seo Joon made gestures to Park Bo Young which suggested that he had sprayed down his hair, and rejected the headband. After seeing this, Park Bo Young nodded and held the second headband that had been meant for Park Seo Joon. 

Many criticized Park Seo Joon's behavior, saying that it was rude to the people who had come to watch his new film and that his fan service was very lacking. Further, many expressed that it was odd how Park Seo Joon had worn the headband during the greeting event for his film 'Dream', but rejected it diuring the event for 'Concrete Utopia'.
