f(x) member Amber revealed that she often takes the public transportation system.

On the July 2 broadcast of TV Mnet "Beatles Code 2," Amber made an appearance on the show and commented, "I take bus number 241."

When MC Shin Dong asked if anyone uses public transportation, f(x) members Luna and Amber honestly answered that they use the bus and subway.

Surprised by their honest answer, Tak Jae Hoon asked, "Which bus number do you take?" and misunderstanding his question, Amber answered "I take it very often."

The MCs repeated their question for Amber, to which she then correctly answered, "Bus 241."
