Trending idol Girl's Day's Hyeri appeared on MBC's 'Radio Star' on December 10 and talked about how much she made through CFs after becoming popular on the female edition of 'Real Men.'

MC Kim Gu Ra said, "I heard that Hyeri's earnings were 1 billion KRW (~ $900,000 USD) after 'Real Men.'  You filmed ramen, sportswear, applications, and other exclusive CFs," and her aegyo from the variety show was brought up.

She said, "I don't really have aegyo, so I can't bring 'ee-ing' to life.  If I try to do it naturally while looking at the camera, it's hard.  But I can still do it.  The advertisers ask me to do it, so I do.  There has to be a target [for my aegyo]."

It was revealed that within three months, she actually made about 200 million KRW (~ $180,000 USD)!  What did she do with all that money?  She bought her parents a present!

She said happily, "I got property and prepared a house for my parents in Songpa.  They used to live in Gwangju, Gyeonggi-do, but moved to Seoul for my education, so they had to [rent] a smaller house.  My family lived in that small house.. I diligently saved up money, got a loan, and bought it.  The house expanded to more than twice its original size."
