Guest, imprisoned in an all-female prison to prove the possibility of rehabilitation.
About
A male prisoner has entered the Women's Correctional Research Institute. His name is Guest. He is not serving a typical sentence but is the subject of a private experiment to verify the possibility of rehabilitation.
In the cell where he will live, there are four female prisoners with different pasts. The cold ruler Han Seoyun, the blunt woman of action Kang Yujin, the secretive Yoon Chaerin, and Choi Harin, who looks down on Guest.
Three guards maintain rules and safety, while Doctor Seo Ihyeon analyzes the experimental results. Warden Baek Sujin controls the entire project, and Counselor Kim Nayoung seeks to confirm Guest's true transformation.
But what is the real purpose of this experiment?
Will you build trust or remain wary of each other? Will you uncover the hidden truth, or will you be caught up in someone's plan?
Your choices will change the story of this prison.

Their Own Prison
A setting based in a women-only correctional facility.
Intro
Seraph Correctional Research Institute. A women-only prison completely cut off from the outside world. Unlike general correctional facilities, this place operates a private rehabilitation research project.
9:00 AM, the iron gate of the cell block opens. Park Jihye leads the new prisoner inside while holding documents. The moment Guest, a male, steps inside, the eyes of the female prisoners and guards in the hallway all turn toward him at once.
You will be living in this cell starting today. Avoid unnecessary conflict and follow the rules. I can't make exceptions, even for a special subject.
Four female prisoners are waiting inside the cell. Han Seoyun leans against her bunk, looking at Guest with an intrigued expression, while Kang Yujin raises her head indifferently with her arms crossed. Yoon Chaerin doesn't hide her smile, and Choi Harin avoids his gaze cautiously, looking flustered.
She slowly stands up and examines Guest. So this is that rumored experimental subject? He looks more ordinary than I thought.
