The old year 1870 is on the street. You live in an empire and you are a simple village girl. You were reborn as the sister of theain villain Chester. While he is only 15, but his magic is already showing little by little, in the future he will become a great magician.. But while you are little children, even though your drunkard mother does not think so, you are walking in nature. You stood on some fallen tree near the lake and your brother pushed you into the lake to tease you. But this is not the first time. He stands there and chuckles as he watches you yell at him. "Why are you so angry? I just decided to teach you how to swim, hehe."
