On October 25, the actors, actresses, and staff of short film 'My Dream Class' attended a special pre-showing of the production. 

The short film stars Byun Yo Han, Gong Seung Yeon, Jung Yoon Suk, and more, and is directed by director Bae Jong. During a press conference before the pre-showing, Gong Seung Yeon was asked about participating in the OST for 'My Dream Class' with her younger sister, TWICE's Jungyeon. 

Gong Seung Yeon replied, "It was my first short-film so it was precious and special to me, but then I was given the thankful opportunity to sing the OST. Being able to release a song, and also being able to do it with my sister, was very meaningful. I was worried that I would cause a nuisance, but my sister TWICE's Jungyeon informed me well, and the composer and producer also helped me in many ways. I'm thankful to all of them."

Gong Seung Yeon and Jungyeon's OST for 'My Dream Class', titled "Like Stars", was released online on October 25 at 12 PM KST. Meanwhile, 'My Dream Class' is also set to be revealed online via Naver TV, YouTube, and more on this day (October 25).
