Cui Dabu (Lee Jong Suk), a taxi driver, Cui Renhe (Park Shin Hye), a journalist who can't lie, Xu (), a second-generation chaebol who has never been in contact with civilians, and Yin Youlai (), a journalist who stares at Fan, are four young people who work as social ministry reporters for 24 hours on TV to seek the truth.

Cui Dabu was originally named Qi Heming. When he was young, when the fireman's father disappeared in a fire fighting mission, which caused reporters to question and condemn him, his mother was forced to commit suicide by jumping into the sea with him, but he was unexpectedly rescued and adopted by Cui Renhe's grandfather, and became a family with Cui Renhe, a niece of the same age but different generations. The benefactor who saved him was the family of the reporter who destroyed his family. Between revenge and gratitude, he chose to repay with Cui Dabu. Cui Renhe also suffers from Pinocchio syndrome and burps when lying down, so it is difficult to engage in other occupations. Finally, he faced up to his illness and chose to be a reporter of the Ministry of Social Affairs who reported the real situation [7-8].
