If you want revenge, it has to be the kind that causes the other person the greatest pain. Synopsis: When a truck ran a red light and took Earn's parents' lives forever, Earn was left alone with her grandfather. One day, however, the grandfather who had promised to protect and care for her adopted a homeless child. Earn had disliked Thoop from the moment he came to live with them at age eight, and things remained that way as they each grew up in their own way. Everything grew worse when Earn learned the truth: Thoop's father was the truck driver who ran the red light that day. The resentment buried in her heart slowly erupted, and Earn was determined to do whatever it took to get revenge, hurt him as much as possible, and make him suffer in place of his father, who was at fault.
