“Ashin of the North” is screenwriter Kim Eun-Hee’s concession to “Kingdom” fans, who are eagerly awaiting the third season of the popular Netflix series.

“Racket Boys” (라켓소년단)

“Racket Boys” is a sweet series centering around a teenager, who’s forced to quit baseball when his father moves them from Seoul to the countryside. Disappointed and bitter, Hae-Kang begrudgingly joins the badminton team — which his father coaches — on the condition that if the team wins a medal, his dad will get them Wi-Fi at their house.
