"Running Man" Gaeri showed off his affection toward Song Ji Hyo.

On the recent episode of SBS entertainment program "I Like Sundays - Running Man" which aired on January 5, 2014, Snog Ji Hyo with her buddy Lee Song Wook left for Po Hang, and Gaeri with Rainbow's Jae Gyung went to Na Joo to execute the "Procure the fresh food ingredients" mission.

Gaeri in the interview said, "Although my current buddy is Na Joo, I want to buddy up with Song Ji Hyo."

Gaeri then got on a phone call with Song Ji Hyo. When Song Ji Hyo asked, "Where are you?" Gaeri said, "Me? Of course in your heart, you fool. Today is Monday." Gaeri then asked Song Ji Hyo who her buddy was. Song Ji Hyo, without letting him know who her buddy was, asked his.

Gaeri then asked, "Why? Do you feel jealous in case it is a girl?" and Song Ji Hyo said, "I do," making people laugh.

Gaeri then said, "Put your buddy on the phone. I need to tell him what you like and do not like." Song Ji Hyo then said, "He knows me as much as you know me." Gaeri then said, bewildered, "Which guy knows you better than I do? Did you go clubbing again last week?" making the audiences laugh.

The day's episode of "I Like Sundays - Running Man" featured "Running Man - Cooking King."
