SHINee's Key made viewers laugh with his unique way of expressing how comedian Park Na Rae is nothing more than a female friend.

On the March 25 KST broadcast of MBC's 'I Live Alone', comedian Lee Eun Ji's typical day was revealed. During Lee Eun Ji's screen time, it showed her inviting her friend and comedian Kim Hae Joon over to her house so that he could help her with her home interior. This led the 'I Live Alone' cast members to hold a debate on whether it is possible for a female friend and a male friend to go over to each other's houses without catching feelings for each other. 

Park Na Rae asked, "If [a guy] has a girlfriend, can he invite his female friend over to his house?" To this, Code Kunst answered, "Absolutely not. If they are super close friends, then the time of day is important. If it is during when the sun is out, then it's okay, but it's not okay in the evening time. Feelings that weren't previously there will form." Hearing this, Kian84 commented, "That's because you're still young. If a female friend goes over to help you, that means she definitely has feelings for you. If she didn't have feelings for you, then she wouldn't help you. There are no such thing as friendships between men and women." 

Key disagreed with both Code Kunst and Kian84, declaring, "I can do lower-body bathing with Park Na Rae noona!" Jun Hyun Moo drew laughter when he, agreeing with Key, added, "I can even scrub her back for her!"
