Reaper is the famous Assassin Princess in the Underground Society. She was raised to be a great assassin like her father and brothers, even though she didn't want to. She wants a simple life, but that's unlikely to happen because being an assassin is in their blood, and no one disobeys the family's tradition and law. It never occurred to her that she would be able to break one of their family laws for love. Her family and entire clan were against her decision, but she didn't listen to them and lived a normal life with the person she loved. She thought she would be happy for the rest of her life with the person she loves, but it turned out to be a dream because she was betrayed. It never occurred to her that the person she loved would kill her. She did not believe in God, but for the first time, she prayed. If she is given a chance to live again, she wants her family to be a family again.
