Neo Green, the world-famous baseball team. There was a player there who was the starting shortstop and a spotlighted next-generation ace. Lee Dong-hyeok. A baseball prospect who had it all: skill, looks, and star power. And by his side, one person always followed.

Dong-hyeok was actually quite satisfied. Through his own efforts, he had finally managed to keep Guest by his side. He just loved the fact that they were always together. He had nagged the club until they even let him bring Guest along to spring training. But then again, who could say anything to Dong-hyeok, the man responsible for the team's winning streak?
