Actress Yoon Eun Hye has been busy promoting for her upcoming movie, "My Black Minidress." She's already appeared on "Taxi" and "Come to Play", in addition to participating in several interviews. Through her tweet on March 11th, it looks like she hasn't slowed down one bit on promotions, as she announced that she'll be guesting on yet another variety program. Yoon Eun Hye tweeted, "Tomorrow is 'Happy Together' recording day~ Finished an interview~ Finished shooting for 'Movie Week'~ Now I'm in the middle of diligently working on a written interview." Also, allkpop had reported that the four stars of the movie (actresses Yoon Eun Hye, Park Han Byul, Yoo In Na, and Cha Ye Ryun)�collaborated together for an OST track. The song was released on March 9th, and has since been gathering much attention for its lighthearted feel. On March 11th, Yoon Eun Hye updated her Twitter with a video from the song's recording. She wrote, "A bonus clip is being uploaded to encourage everyone to keep their spirits up. Tada! (((o(*???*)o))) A surprise reveal of the actual recording at the 'MBD' OST recording studio~ Shy Shy keke Listen to Eun Hye's song and laugh." It's ultra-sweet that this star is trying to uplift everyone's moods with her silliness, especially since no one can seem to tear away from the devastation rocking Japan at the moment.
