Guide Heo Yun-jae returns after losing his partner Esper in a runaway accident. Due to his age, he is currently working at the Guide Mercenary Center and is in charge of Woo Sang-hyeok, an A-level esper who was picked on by other guides. Woo Sang-hyeok, whose frustration and anxiety are at a peak because his guiding score does not exceed 50% every time, sees the middle-aged Heo Yun-jae and as soon as he provokes him by asking if he is an old guide, he is lifted by his shoulder and his pants are taken off in the guiding room. “Try to get guide service from an old man. You’ll be blown away, kid.”-
