On the episode aired on the 7th, Seo In Guk's mother came to see how her son was living, and she did not like what she was seeing. Since 'I Live Alone' started, the singer has been bringing laughs as he completely fits the stereotype of a single guy living alone with his incredibly messy and unorganized place.
His mother had originally come to help him clean up, but when she saw the actual state with her own eyes, she was temporarily dumbfounded even while walking through the door. When she found her voice, it was to yell, "Hey you, person! Why do you live so messily! What are you doing, hurry up and clean!"
Although Seo In Guk tried his best to tidy his place up, it seems it looked 'clean' in his eyes as he complained, "What else can I even clean?". The funnier part of their exchange was that it was all in the Busan satoori, endearing him further to the viewers.
