Mother Choi

She never physically appears in the game, but her sons most likely got their red hair from her. it's possible she may also has gold eyes, or the twins probably just got their gold eyes from their father.

She was a cruel, abusive, violent, spiteful woman who exhibits severe sociopathic tendencies. She suffers from severe alcohol addiction, and used an invective language with anybody she came across. She was portrayed as a selfish, foul, and scornful person who used violence whenever she didn’t get her way. Saeran described her as self-damaging, that whenever she got drunk, she’d get mad and end up blaming herself and the world. Because the twin's father was a high-profile and married politician, she used the fact that she was his mistress and that she had children by him to her advantage to blackmail and to extort money from him.

She never showed her sons any love and was extremely abusive to them. Her abuse was emotional, mental, and physical. And it consisted of calling her sons worthless monsters, beating them, tying them up, strangling them, starving them, and much more...

She was described by Saeyoung as outrageous, and half-insane. Saying that she never considered them as her children, but as tools to threaten their dad. While Saeran described her as an intemperate, malicious woman, who made his life a dark tunnel filled with misfortune.

She did not let her sons go to school, and kept them in the house because of the fear of losing them to their father. Although, she would sometimes send Saeyoung on errands. she constantly used their father's position to strike fear in them and told the twins that their father would send people to kidnap and kill them, and if it wasn’t for her, they would already be dead.

According to Saeran, She tried to protect them at all costs. And Whether or not she had genuinely loved her sons at some point in time or had only raised them into adolescents for blackmail material is unknown. However, she was hysterical when Saeyoung had disappeared to work for the intelligence agency. And it has been stated by Saeran in an outgoing phone call that she used to hold him tight all day long after everytime one of his Father’s men visited, And that even though they lived in extreme poverty, she made sure that her sons got something to eat at least once per day.

Not much is known about her past. But 21 years before the events of the game, she was sexually involved with the current prime minister which resulted in the twins birth. How she became the way she is, how she got herself in poverty, and how she got entangled with a high-profile politician remains unknown.
