Ace of English Premier League team Greenford, world star, star of Asian football, ace of the South Korean national football team and troublemaker Kim Moo-gyum. He wants to repay his middle school teacher, who guided him on the path to soccer, so he risks public criticism and forfeits his salary to join K-League team City Seoul on loan for just one year. There, he meets Lee Ha-joon, a new physical coach who is his age. He’s a strangely unmemorable man, even though they’ve been to one World Cup together and have been part of the national team several times. “How dare you discriminate against me, Kim Moo-gyum, when you're just a new coach?” – But it didn't take long for Moo-gyum to notice Ha-joon's ‘weirdness’ in avoiding him. “No wonder, I thought he was too reserved for a defender.”
