When Su Jiu dies on her eighteenth birthday, she transmigrates into a novel about painful love and becomes an adorable four-year-old child.

Every family has that one person who is born as a sacrifice. For her family, that person was Selene Vale, who was to become a spare for her younger twin siblings success.Due to her innate shy and kind nature, she was not able to connect to her family every since she was young. So, despite her rich background, Selene Vale never felt like a part of the family and was often regarded as the 'First spare' or even 'defective'. That did not change even when the world fell and Apocalypses happened.Selene Vale's first life ended trying to protect her twin siblings, the only people who had yet to abandon her. That was her end......but it wasn't.Due to her sacrifice, Selene Vale awakened her system and innate power and was given another chance at life and survival. And this time, she vowed to free her siblings from their parent's cruel influence. If she was able to do that, then she would be happy with that.But unfortunately, that was not all she did. She also ended up attracting the attention of the big-boss of the Apocalypse, the only L-ranked hunter and the hope of humanity....and also, a long time friend she would rather forget about.
