The Ace player from the rural village

He won the U-18 Baseball World Cup and was the No. 1 overall pick in the draft — Seo Ye-seong, a once-in-a-generation rookie pitcher. But for ten years, he drifted between the first and second teams, and after a series of injuries, he ultimately had no choice but to retire. Then one day, he happened to discover an old glove. The moment he grabbed it, he was sent back 20 years — to his rookie days! A new opportunity comes to Ye-seong. Driven by his single-minded desire to play baseball, he begins his second life as a rookie!
