Hallyu star So Ji Sub returns to the small screen next week when the Korean drama "Cain and Abel" begins airing here.

Already a hit in South Korea, the 20-episode series features So Ji Sub ("I'm Sorry I Love You," aka "Misa") as Abel (Lee Cho-in) and Shin Hyun Joon as Cain (Lee Sun-woo). Chae Jung Ahn and Han Hi Min also star.

As the title suggests, "Cain and Abel" is a drama about sibling rivalry. Lee Sun-woo and Lee Cho-in, adoptive brothers and accomplished neurosurgeons, become rivals when the family's hospital is willed to the adopted Cho-in instead of biological son Sun-woo. Enraged, Sun-woo and his mother send Cho-in to China, where he saves a North Korean refugee and falls in love with her. He survives a murder attempt but amnesia forces him to piece his former life back together.
