Beware The Ides Of Gyeongju

For twin siblings Esen and Hulan, nothing gives them more joy in life than working with their respective vehicle partners, Tayo the City Bus, and Sonny the Passenger Train Power Car. Though such joy comes with a lot of mad nonsense, and their city of Gyeongju is far from a boring place. (Fanfic of the South Korean Cartoons Tayo The Little Bus & Titipo The Little Train. No Flames)
