School 2017 has confirmed that Gugudans Sejeong will play one of the female leads in the drama.
Earlier, it was reported that Sejeong would be joining the cast of School 2017 and now KBS has confirmed that she will indeed be joining.
Sejeong will play the role of Ra Eun Ho, a bright and cheerful girl who has a dream of being in a campus couple. Even though her class rank is terribly low, she gets admitted to a prestigious university thanks to her talent in creating webtoons. She intentionally acts as a bad student so she can travel between schools to find material for her webtoons.
