Genie is a workaholic software developer with serious back pain who's pressured into attending his coworker's birthday party at a gay club. There, he meets a flirty man named Seong-Geun who's famous for "healing" men in the bedroom with his "needle." Thinking Seong-Geun is an actual doctor, Genie follows him to a hotel after some drinks and wakes up naked next to him! Although a one-night stand wasn't in his plans, Genie finds that his back pain is completely gone. And with a major work deadline looming over his head, Seong-Geun's magic touch might be his only salvation.
