On MBC's 'Radio Star' this week, CNBLUE's Jonghyun dished on his affections toward f(x)'s Krystal (or Soo Jung).

The MCs said to Minhyuk, who played her boyfriend in 'Heirs,' "You said that you automatically smile because our Soo Jung is so cute."  Minhyuk replied, "She's really cheerful, was really good to the oppas when we filmed in the school, and so on."

Kyuhyun then said, "Does Jonghyun like Krystal too?  Your expression is a bit dark," so Jonghyun said, "I monitored the show and her character was really refreshing and pretty, so I became a fan.  That is why the members and I have talked to her altogether on the phone once."

Would anyone else like to see Minhyuk, Jonghyun, and Krystal form a love triangle in their next drama production?
