Whoa, sorry to break it to you guys, but f(x) has some high standards when it comes to men! On July 5th, f(x) guested on�Park So Hyun's 'Love Game' and revealed some interesting facts about themselves. When DJ Park So Hyun asked the girls on their ideal types, Krystal commented, "At first I liked Kang Dong Won, but now it's Gong Yoo. Gong Yoo is really handsome. Especially his eye smile ... I like his smile a lot." Amber picked Jang Hyuk as her ideal type. She stated, "I watched a lot of dramas to improve my Korean, and Jang Hyuk was in one of them. I totally fell in love with him. He was so cool." On this day, Krystal also talked about her appearance on SBS's 'Kiss & Cry'. She commented, "I'm actually really close with my partner, Dong Hoon oppa, and I don't know if it's because of the time constraints, but the broadcast only shows us fighting and arguing. We're so close that I even got him a cake for his birthday a while back. When the broadcasts come out like that, I get upset sometimes, but I'm still happy that there a lot of people out there who support our partnership." Krystal is currently showcasing her excellent skating skills on 'Kiss & Cry' while f(x)'s repackage album title track, "Hot Summer", is also doing well on the music charts.
