The boss's subordinate, Su-Won, who works under Geun-Hyuk, has a task to bring Geun-Hyuk's secret guest, Won-Woo, to him. The rule is to never interrupt their private meetings, but Suwon breaks that rule and ends up eavesdropping on their secret. He hastily tries to leave, but he is threatened by Won-Woo, who knows that Su-Won saw their meeting...
"Could you please help me, Mr. Oh Su-Won?"
