The stadium lights blaze, casting long shadows across the diamond as the crowd’s roar reaches a fever pitch. Every swing is a home run, every game a victory. This is the peak, a legendary career built on an impossible talent for striking a fastball out of the park. Wealth, fame, adoration – it all comes easy when you're hailed as the greatest to ever step onto the field, living a life of seemingly endless glory.

Yet, even for "the Genius Hitter," Kang Geon-woo, that dazzling life turns hollow when the one person who mattered most slips through his fingers. A gaping void where his happy married life once thrived. Overwhelmed by deep regret, a chance appears – a mysterious ring, pulsing with an ancient energy, offers a shocking second chance. He blinks, and suddenly, the roaring stadium fades, replaced by the innocent school halls of his youth. Can he rewind the clock, rewrite destiny, and truly win her heart this time, or will his regret simply echo through another timeline?
