Sunny, Lee Kuk Ju, and Nana engaged in girl talk on the January 13 installment of SBS's 'Roommate', talking about different relationships, such as 'some' and marriage.  

Lee Kuk Ju started off the conversation with, "Do you guys have any thoughts on dating these days? Sometimes don't you just get that feeling of loneliness?"

Nana said that she never felt that way, but after she hit a certain age, she started to feel differently and thought about getting married. She said "Before I turned 20, I did not want to marry, but I changed my mind afterwards."  Sunny replied, "I am still fine with being single. Is it a must that I have to get married? I think it's the same with dating. I don't think you have to date, you just date if you want to."

Despite her thoughts on being alone, Sunny said, "I do really want to be in a 'some' with someone right now though." She explained that this was just because she liked the fluttering feelings of excitement, saying,"You understand what I'm saying right? That pit-a-pat type of feeling. If I get a message [from that person], I want to hold my phone and wonder things like, 'oh? what does he mean?' and whether I should reply a minute later or three minutes later." 

The girls also talked about the push-and-pull method, which is when a person goes back and forth between acting cold (pushing a person away) and being flirty (pulling the person back in).  

Nana said, "I don't do push-and-pull at all. I don't understand why people who love each other push and pull. I like it better when guys just boldly and aggressively confess their feelings."  On the other hand, Lee Kuk Ju said, "If you want the other person to feel some sort of charm from you, you must do push-and-pull." Sunny also agreed as she said she preferred a guy who wasn't clingy.
