On December 19 episode of SBS' television show 'My Little Old Boy', SiWon made a guest appearance.
In this episode, SiWon revealed his home on television for the very first time.
He kept his home unbelievably clean and neat, to the point that surprised the panel in the studio.
SiWon was seen cleaning and tidying up his place as soon as he returned home.

While SiWon prepared dinner for them, they asked him whether he has ever had girls over at his place.
SiWon smiled and responded, "Well, it can't have been none, right? I mean, why not?"

Then, they laughed and commented, "Wow. That's great, we guess!"
