Seol In-ah Cracks Yim Si-wan's Locked Room, but Gets Fired Before the Lights Fall

Yim Si-wan's Yoon Yi-joon ordered Seol In-ah's Kang Jae-hee to leave the moment he caught her walking out of his forbidden room with evidence in hand. That confrontation was the turn of the October 26 episode of tvN's Monday-Tuesday drama My Guilty Human, and it ended with a falling light and a shove that may have saved his life.

The episode opened with Jae-hee catching a shirtless Yi-joon as he stumbled, then dropping him just as quickly. When he bristled, she tried to steer him back to the apology he had seemed about to make. He changed course and told her to figure it out herself. Outside the room she threw a punch at thin air, saying one real hit would settle everything.

Jae-hee offered to check which outlet the reporter tailing Yi-joon worked for, but he already knew: his second older sister, Yoon Na-jung (Park Ah-in), was behind it. He then went to the columbarium of Han Eun-young (Jung Yu-min), his late secretary. Jae-hee probed whether he had cared for her. He said he came to apologize because he was the one who made her that way, and asked if Jae-hee was afraid of ending up like that. If so, he said, she should quit. She refused, saying she needed the money and would stay by his side.

A night of watching him sleep

After a nightmare, Yi-joon summoned Jae-hee and fussed that his daily milk intake had gone up. His order: he can't sleep, can't drink milk, so she must keep watch until he drifts off. She was appalled, but followed him in, reasoning that once he slept she could open the room at the end of the hall.

Films and books did nothing for him, and she nodded off first. Yi-joon watched her with a soft look, then startled himself and muttered that he didn't like it. He still pulled the blanket over her.

The room at the end of the hall

Jae-hee then caught a man watching Yi-joon's house: Secretary Jung. He knelt and begged to return to work, and Yi-joon allowed it at once. Jae-hee heard from him that the rumor of Yi-joon dating Secretary Han was false, and he was sure of it.

She slipped into the end room and came out with evidence, only to find Yi-joon waiting. He declared her fired on the spot. She said what she heard at the columbarium had weighed on her, and that whether or not she is his suspect now matters to her, because something unknown is happening in this house. As she spoke, a light fell, and she pushed Yi-joon out of the way.

A lighter thread followed Kim Si-hyun (Kim Jung-hyun) and Lee Hye-jung (Yeon Woo), who spent the night together. The next morning she said she'd had fun, and he asked why it was already past tense. She answered by repeating his own line back to him: a man arriving is welcome, a man leaving is even more welcome.
