On the first episode of SBS's new variety program 'Laws of the Jungle in New York,' which aired on June 11, Girls' Generation's Sooyoung came up during her boyfriend Jung Kyung Ho's phone conversation with actress Choi Yeo Jin.

Another person on the show, Kim Sung Soo, heard incorrectly that Choi Yeo Jin was going to be a female cast member so he dialed her up.  He warned her, "We're in the middle of recording, so you can't curse (over the phone)."

She proved to be good friends with Jung Kyung Ho, saying, "I filmed 'Sorry, I Love you' with Jung Kyung Ho."  When asked what she thought of him, she suddenly said, "Kyung Ho, I love you."

Kim Sung Soo said, "You know he has a girlfriend, right?  You, you know what group his girlfriend is in, right?" bringing up Girls' Generation's Sooyoung.  She said she knew, then asked jokingly, "Aren't I better?" so Kim Sung Soo asked Jung Kyung Ho whom he liked better, Choi Yeo Jin or Sooyoung.

A taken aback and flustered Jung Kyung Ho said, "I like them both."  As he also called Choi Yeo Jin 'noona,' she asked, "Why are you suddenly calling me noona?  Just be comfortable with me.  Don't draw a line at noona for me," jokingly hinting she would not be sister zoned, which made poor Jung Kyung Ho even more taken aback.
