Seo In Guk previously revealed that he no longer wants to 'live alone' partly because of one particular bad habit.

On the April 26th broadcast of KBS 2TV's 'Full House', the seemingly perfect bachelor Seo In Guk revealed, "There is something that my mother nagged at me for and told me to fix."

The singer then shared his bad habit revealing, "I am currently on another program, but the inside of my house is not in good condition. One of my habits is that like a snake sheds its skin, I take off my clothes right there and then. Because I live so freely, I think I live in a dirty house."

Lee Kyung Kyu responded, "In the case of habits like Seo In Guk's, the correct terminology is not 'take off clothes', but 'come out of clothes'. You come out of your clothes and go back inside of them the next morning", giving his hilarious two cents on Seo In Guk's bad habit.

Viewers commented, "So there was a reason why he said his house is not in good condition", "I'm surprised at his bad habit", and "He'll just have to fix it like everyone else."
