Grandpas Over Flowers is a South Korean travel-reality show that airs on tvN. The title is a word play/parody of Boys Over Flowers, a popular Japanese manga about four handsome young men. The series stars four veteran actors in their seventies — Lee Soon-jae, Shin Goo, Park Geun-hyung and Baek Il-seob — as they go on a backpacking tour to overseas travel destinations alongside Lee Seo-jin, an actor in his forties.
