This is such a buh? type casting I don’t even know where to start mainly because I have no idea who this actress is. The leading lady for So Ji Sub‘s next drama Terius Behind Me will be Jung In Sun, who I had to google to find out what per previous acting resumes are. Her most recent drama was as the leading lady in cable drama Welcome to Waikiki, and also making tabloid news for dating her Waikiki male lead Lee Yi Kyung and then the two breaking up a month later. I legit have never seen her onscreen before since I didn’t watch Waikiki but if she’s a good actress then this casting is fine though still strange since So Ji Sub is such an established big name leading man and his drama leading ladies have always been top actress counterparts like Shin Mina for Oh My Venus and Gong Hyo Jin in The Master’s Sun. Jung in Sun’s casting came after Yoo In Na turned down the role and even earlier Lee Yoo Young also didn’t accept.
