Hwang Jeong-Ho, a national archery team member, retires after suffering a fatal injury that turns his shoulder into an erogenous zone. After that, Jeong-Ho avoids human contact and works as a delivery man. By chance, he ends up delivering to the house of Kang Jun-Hyeok, a current famous national archery team member... But Jun-Hyeok suddenly calls Jeong-Ho's name and grabs his shoulder, leaving Jeong-Ho helpless in front of him?! Before he can even come to his senses, the large man in front of him throws an even more embarrassing fastball at Jeong-Ho. "It seems like it's because of me, so I'll take responsibility and help you, senior."
How on earth does he mean to help?(Source: Bomtoon, translated)
