the first drama i watched was Gu family book and it got me into korean dramas all together. Her acting was really good and it was only after the series did i find out she was actually a singer in Miss A. I then watched her other drama and found that she has a real acting style but can be many different roles. I would really like to see her in something new!
My dream cast for a drama would be
Suzy
IU
Kim Woo bin
Lee Min ho (i know them to again after heirs but still)
Jung Il woo
Yoon Si Yoon
