Forgot the name ;0;

So I read this a while ago and would love to continue it but I can’t find it and can’t remember the name ;0;. It was about the girl who was forced to be the villain by the system and if she misses all three quests she gets really sick. There like two love interests, one has black hair and the other I think has white or blonde hair. I know Mc has pink hair and so does her brother! And the original main character is blonde, if someone knows the name please let me know!
