Park Bo Gum is the man of his words. The rising Hallyu star kept his promise and enthralled fans by appearing in a Hanbok at an official signing event of the drama, Moonlight Drawn by Clouds.

The 23-year-old apparently made a rating promise, and mesmerized his worshippers at the fan event in Gwanghwamun. Previously, during the drama's press conference in August, the actor committed to his fans he would host a special event clad in traditional Korean attire if the viewer ratings of the Crown Prince drama surpassed 20 percent. In addition, the drama's representative agency also came forward and assured to rope in four more actors for the celebration.

On 19 October, the lead actors, Park Bo Gum, Kim Yoo Jung, Jinyoung, and Kwak Dong Yeon, arrived at Gyeongbokgung palace for the fan meet-cum-autograph event. The event was secured by tickets, and only 200 lucky fans got the opportunity to meet the celebrities in person. However, the event drew a crowd of over 5,000 people, Soompi reported.

At the event, Bo Gum addressed his fans by saying: "I'm so grateful and it's such an honor that we've been able to carry out our ratings promise to celebrate surpassing 20 percent in the ratings. I'm truly thankful that so many people came."
