It's safe to say the box office hit 'Introduction to Architecture' was Suzy's breakout role in the film/drama industry. With the help of that film, her popularity soared not only among fans but the general public. But what if someone else had taken on that coveted role?

Girls' Generation's Seohyun was a guest during the filming for the upcoming episode of 'Radio Star' and she talked about receiving an offer for that same role at the time.

MC Kim Guk Jin said, "I heard that you almost took on Suzy's role."

Seohyun admitted that that was true, and she said, "I really wanted to do it." And that she can't help but be upset at her agency about the matter. But what is exact story behind why she couldn't take the role? You'll have to tune in to the episode airing later today to find out! 

If you tune in you'll also see Seohyun perfectly mimic the 'Minions's "Banana Song" on the show!
