Due to his parents’ sudden decision to live in the countryside, Daeyoung moves to the countryside with his older brother Daesu, where he meets Seongheon and Gangjin, the sons of his father’s friend.
“Daesu’s younger brother is kkakdugi.”
“Yeah, make him play goalkeeper.”
When he was young, he could stand shoulder-to-shoulder with the hyungs as the kkakdugi.
But what’s a 3-year age gap—he gradually grew more and more distant from the hyungs.
Then one day.
When told the hyungs were hanging out together, Daeyoung secretly followed along to Seongheon’s house—
“Ah, you crazy bastards. Why are you crawling in at this hour?”
“We came to check what you’re up to. You’re not even answering calls.”
“Fuck, so fucking annoying. Why the hell are you showing up without notice? Are you brain-dead?”
‘……Holy shit.’
He witnesses the ‘real’ side of Seongheon, who had always been kind to him.

Thinking he’s been fooled all this time, he decides on a cute(?) revenge!
