Why Does Yim Si-wan Ban Seol In-ah From One Room in My Guilty Human?

In the second episode of tvN's new Monday-Tuesday drama My Guilty Human, aired on the 20th, Yim Si-wan's Yoon Yi-joon told his new aide Kang Jae-hee (Seol In-ah): "I'm going to keep watching you, and you'll have to keep proving yourself." Kang is an undercover operative, so the warning lands harder than he knows.

The premise is a familiar one for the genre: a plant inside a suspicious target's home, with a team listening in. Here the team is led by Park Bong-i (Kim In-kwon), who watches through a camera built into Kang's glasses.

A first day under suspicion

On her first morning at Yoon's house, Kang wore those glasses. Yoon noticed the lenses had no prescription and pressed her on it. Park hurriedly prepared to move in, worried Kang might do something rash. She saved the cover with an apology, saying she had hidden behind the glasses because she was tired of being told she looked like a woman.

Once inside, Kang mapped the house and told Park and Kim Seok-jin (Nam Hae-jun) from the bathroom that Yoon's guard was extremely high, so she would start by building trust. Leaving the bathroom, she dodged the cat, Jerry, and accidentally shoved Yoon, who ended up with his head in the litter box.

Kang's real task is to find the phone of Han Eun-young (Jung Yu-min), who has died. Yoon gave her three rules for an aide: speak and act efficiently, and keep both physical and emotional distance. He added a last one: never enter the far-left room on the second floor.

Leads and a taste test

Kim Si-hyeon (Kim Jung-hyun) visited the house, and Kang overheard enough to learn that Team Leader Park (Kim Do-yoon) is tied to the case. Back with her team, she vented that Yoon was a lunatic whose personality invites punches. She also reported that Yoon had not gone to work for about two weeks and that Han had seen something she should not have. Jung Wan-gu (Kim Ki-bang), working as a cleaner at the company, found that Team Leader Park had carried something down from Yoon's office floor.

Yoon, in a low mood, was relieved to learn Kang felt the same odd changes in the house. "So I'm not going crazy," he said. He then made her his food taster. She spat out the dish, called it terrible, and cooked bibimbap herself.

At an art center, Yoon met Team Leader Park to confirm that what Han saw had been destroyed, and told him to lie low. He then caught Kang tailing him despite orders to wait in the car. When a reporter appeared, she ran after the reporter and explained she had been chasing him.

The episode closed the next day. Kang entered Yoon's room as he stood shirtless after a shower, and he hesitated over apologizing for the previous day. As she tried to leave quickly, she pushed him, then threw herself to save him from falling and saw his towel come loose.

The mix of suspense and slapstick suggests the drama intends to alternate case-driven tension with comedy between its two leads.
