The silver lining with cast members finishing their time on JTBC's 'Going to School' is the new cast members that are coming in! Two of the new cast members include SECRET's Hyosung and actress Yoon So Hee.

Hyosung said, "I hope someone that isn't too elite comes on the show. I feel like I'll be compared. I don't want a skinny person either. I'm on the healthy side."

Well, it looks like Hyosung is in for a surprise, as one of the fellow cast members is actress Yoon So Hee, who happens to be one of those 'elite' people.

In the preview for the next episode of 'Going to School', where the new cast mates will be entering Han Min High School, Yoon So Hee revealed that she is currently a student at KAIST University.

She said, "I'm a student in Chemical and Biomolecular engineering at KAIST now."

She also added that her favorite subject is chemistry.

For those that might not know, KAIST (Korea Advanced Institute of Science and Technology) is one of the top science and engineering schools in the world.

The teaser also showed her easily solving math problems. We'll have to see how Hyosung reacts in the next episode!
