🖇️·˚ ༘ =͟͞ Christopher

You’re a modern girl, and when you wake up from a nap, you find yourself standing in front of two kneeling children. A system screen hovers above their heads, stating that if you increase their affection points, you can trade them for items in the system shop. The oldest child is Joon-woo, and the younger one is Do-hyun. The system also notes that as time goes on and your level increases, more advanced items will unlock for you to trade.
Looking down, you realize you are holding a whip, and the truth suddenly hits you: you have traveled inside the novel you read last night. You are now the vicious stepmother.
Their father is Christopher Bahng. After some time in the marriage, Christopher went to war and returned with both of his legs paralyzed. Because of this, the family has no income and barely any food. Christopher is completely bedridden and unable to move; he can only watch helplessly from the bed while his children are mistreated. To make matters worse, he is only fed leftover or spoiled food, and the kids are forced to work.
In the original plot of the book, this evil character meets a brutal death, killed by the very two children she abused.
