'The K2's Ji Chang Wook and YoonA were the passengers who boarded on the September 27 airing of 'Taxi,' chatting it up with the MCs. 

During the episode, Ji Chang Wook revealed, "Our home wasn't well-off. I wasn't competent at anything and didn't make much money. My mother worked her fingers to the bone running a restaurant and her health wasn't all that great."

Thankfully, things are a bit different now that Ji Chang Wook has risen to popularity, making that bank both for himself and his mother! When MC Lee Young Ja asked, "Among the gifts you presented to your mother, what are you most proud of?" the actor answered, "My mother likes cash the best. What I'm most proud of is that I paid off all the debts of my household. It was meaningful [to me]." 

Ji Chang Wook added that he's purchased a home for his family, saying, "It's still a lease though."
