After School roommates JungAh and Jooyeon shared about their special friendship while guest starring on KBS' Star Golden Bell 1st Grade 1st Class. MC Ji Suk Jin opened up the conversation by saying, "The two of you really seem to be close". JungAh responded by stating, "Although we are roommates, we really are best friends." A miffed Ji Suk Jin pushed them by stating, "You must have gotten close by talking about your boyfriends." Surprisingly, JungAh and Jooyeon immediately replied, "Yes." Following that exchange, JungAh honestly explained, "We talked about our previous boyfriends." Then, Ji Suk Jin brought laughter to the set when he comically said, "Your ex-boyfriend? Your boyfriend from 3 days ago..." He then suggested that the two girls give brief words of advice to each other. Jooyeon complied and said, "JungAh-unni  is the style to get cheated easily. I wish that she wouldn't be so lenient about everything." In response, JungAh said, "Jooyeon talks about her private life a lot and I often think, 'She really does trust in me.' However I wish that she wouldn't talk about such useless things. She even talks about how many hours she slept in a day." This episode of Star Golden Bell will air on July 31st.
