Lim Sung is a pitcher who is in his last year as a high school baseball player.
He reunites with Kim Heedo, the batter who hit a two-run homer in the bottom of the ninth inning three years ago.
Heedo is about to quit the baseball team he just joined.

“Why are you obsessed with me?”
“Obsessed?”
I didn’t expect to be asked that.

Lim Sung and Kim Heedo stood on the same ground for a game only once.
I want to compete with Heedo again, I really want to win against him.
Lim Sung’s competitiveness turned into curiosity and a one-sided friendly relationship from wanting to get to know him more.

“Because I want to do it with you.”

The straight end of Heedo’s eyebrow rose slightly.
Sung, who brought about a change for Heedo for the first time, barked out a laugh.
