Im Si-wan debuts as murder suspect heir in tvN's 'My Guilty Human'

A heir, a dead secretary, and a very incriminating belt

나의 유죄인간 (My Guilty Human) premiered on tvN on October 19 at 8:50 PM, taking over the Monday-Tuesday slot from 로또 1등도 출근합니다. The show is adapted from the web novel 여자인걸 왜 모르지? and streams on Tving.

Im Si-wan plays Yoon I-jun, executive director at Taegang Group — the top-ranked conglomerate in the drama's business world — and the frontrunner to succeed Chairman Yoon Tae-sik, who is ill. Episode 1 wastes no time. His secretary Han Eun-young (Jung Yu-min) turns up strangled inside a cabinet, and Yoon I-jun's fingerprints are on both the body and the belt used as the murder weapon. The catch: investigators found no DNA from the perpetrator. No skin tissue. No blood.

The detective who "breathes like a man"

Kang Jae-hee (Seol In-ah) is a former special forces detective. She needs Han Eun-young's missing phone, and the fastest route is getting hired as Yoon I-jun's personal executive secretary. As a man. Here's her reasoning:

"I'm always mistaken for a man just by breathing. This time I'll properly become a man."

The interview doesn't go well. Yoon I-jun fails her on the spot: "There is no executive secretary who attacks their superior under any circumstances." He changes his mind after she physically saves him, telling her she's the first person to ever throw their body to protect him and the first to fold his waist "like a folder." One non-negotiable requirement: she must unconditionally like him. She gets the job.

The disguise lasts one day. Her first morning, Yoon I-jun pulls off her glasses. "I had my suspicions, but you're caught."

The supporting cast

Kim Jung-hyun plays Kim Si-hyun, a lawyer on Taegang's legal team and Yoon I-jun's friend of 16 years. Yeon Woo plays Lee Hye-jeong, secretary to Chairman Yoon Tae-sik. She's described as the face of Taegang, someone who operates on the philosophy that a good secretary is their boss's shadow.
