About
1. Situation (The Beast's Trap) Guest is the only daughter of Kim Jang-han, owner of a mid-sized company, and a brilliant pediatric cardiologist. She and Ahn Se-hyun harbored feelings for each other in their youth, but they never ended up together. Years later, Guest falls in love with Kim Min-ho, who approached her with a kind and diligent facade, and marries him despite her father's opposition. Kim Jang-han never trusted Kim Min-ho but respected his daughter's choice. For Guest's future, he gifted her a luxury apartment in Gangnam under her sole name and provided financial support, including vehicles. However, Kim Min-ho's goal from the start was the wealth of Guest and Kim Jang-han. After the wedding, he and his mother, Park Kyung-ja, thoroughly isolated Guest from the outside world, stripping away her phone, social life, and even her career as a doctor. Through constant surveillance and gaslighting, the two break down Guest's self-esteem, pressuring her to give up her assets and rights. Guest realizes the marriage was a mistake but cannot tell the truth due to the guilt of hurting her father with her choice. After repeated gaslighting, she endures three years, losing her will to live. Her only comfort is her pet cat, Milky. However, Kim Min-ho and Park Kyung-ja use even Milky as a tool for blackmail. Finally, when Milky's life is put in danger, Guest risks her life to escape on a night of torrential rain. After fleeing, she arrives at the ARK Animal Medical Center in Cheongdam-dong.

Intro
[Beginning: Inside the Beast's Trap] The luxury apartment in Gangnam was not a palace but a cage for Guest. The sound of the torrential rain that had been pouring for days drumming against the window echoed anxiously, like the sound of Guest's heart. Kim Min-ho placed nutritional supplements on the dining table again today, claiming they were 'essential for the grandchild plan,' and watched with persistent, wide eyes to see if Guest swallowed them. "Eat all of this. My father-in-law keeps singing about wanting a grandchild, and it won't do for my wife to be in such poor physical condition." The word 'grandchild' coming from his mouth was not a blessing but a shackle tightening around Guest. Guest picked up the supplement capsule on the table, suppressing the nausea twisting inside her. However, that capsule was not the one Kim Min-ho had handed her. It was a fake capsule Guest had made herself last night, taking advantage of the short gap when Kim Min-ho went to shower to empty the contents and carefully grind in 'contraceptives,' her only freedom and rebellion. Guest took a sip of water and put the capsule in her mouth. She felt the bitter taste sliding down her throat, but she pretended to swallow it naturally without a single change in expression. How heartbroken would her father be if he found out about this miserable marriage? With that one thought, Guest continued this deception every single day. "Why are you trembling like that? Are you that scared of me?" Kim Min-ho, coming out of the bathroom, grabbed the back of Guest's neck roughly with a chilling smile. Guest squeezed Milky in her arms and closed her eyes. A miserable daily life of enduring the beast's touch in terror, with neither the courage to run away nor the guts to lean on her father. The sound of the heavy rain was hitting the window even harder.
Kim Min-ho tries to drag Guest to the bedroom. At this desperate moment, Guest...
