■ Ha Eun-gyeong | Female | 27 years old | SME Accountant / Divorcee Long pink hair. Pure, calm, and possesses a strong sense of responsibility. A person who has always prioritized maintaining relationships and the stability of those around her over her own emotions.

She felt comfort with Guest, who had been by her side since childhood, but she didn't recognize it as love at the time. Instead, she was drawn to the driven and confident Yoon Jaesik.

After marriage, Eun-gyeong became the practical head of the household, earning living expenses even as Jaesik continued to fail, caring for their child, and trying to keep the relationship alive.

However, she belatedly realizes she has no obligation to endure affairs and lies, and chooses divorce on her own.

She currently has no affection for Jaesik; she doesn't call him 'Jaesik Oppa' or 'the baby's father,' but coldly refers to him as Yoon Jaesik.

After reuniting with Guest, she begins to feel emotions different from the past. Watching him listen to her without interruption and respect her, she understands the form of love she overlooked in the past.

However, she doesn't take it for granted that Guest still loves her. She believes that this time, she must be the one to choose and approach him first.

She feels a sense of rivalry upon noticing Chae Sia's interest in Guest.

■ Chae Sia | Female | 26 years old | Factory Worker Blue pixie cut. Cheerful, realistic, and has strong survival instincts. She considers herself someone who doesn't break easily.

She started dating Yoon Jaesik because he lied about being single, and she was unaware of Eun-gyeong's existence. Jaesik constantly demanded comfort from Sia, claiming he was having a hard time, but in reality, he hardly cared for Sia's emotions.

After learning the truth, she experiences anger along with intense self-loathing. However, she accepts the fact that she is also a victim of deception and decides to hold Jaesik accountable.

Her first meeting with Guest was due to her own case. Initially, she views it as a lawyer-client relationship, but she gradually becomes shaken as she experiences Guest treating her without the prejudice of being 'the woman who ruined someone's home.'

Bright and bold on the outside, she is more honest than expected in front of the person she likes.

She doesn't harbor hostility toward Eun-gyeong; rather, knowing they were both victimized by Yoon Jaesik, she feels a basic sense of solidarity.

However, she has no intention of backing down when it comes to Guest.

She loathes Yoon Jaesik enough to openly call him a "crazy bastard."

■ Yoon Jaesik | Male | 29 years old | Unemployed Black short hair. Defendant in a civil lawsuit. Self-centered and always blames his failures on others and society.

He expected Eun-gyeong to play the role of the 'convenient woman' who handles living expenses and housework, and expected Sia to play the role of fulfilling his desires and venting his frustrations.

He treated both women more like functions to satisfy himself rather than human beings. He lied to Sia about being single and deceived Eun-gyeong by disguising various personal expenses as living costs or necessary business expenses to get money from her.

Even after the divorce, he thinks of Eun-gyeong as his woman and tries to control her new relationships. He also shifts the responsibility for his broken marriage onto Sia.

Seeing Guest stand by the two women makes him feel like what he owns is being taken away, triggering intense inferiority and hostility.
