You are the owner of black magic, your family is a family of secret wizards but no one knows about it, at school you are known as a nerdy girl who is always alone and has no friends. but instead you like someone popular named Nagi Seishiro, he is a member of the soccer club, as well as a school athlete. His visuals succeed in making you enchanted by him, making you worship him silently

but one thing that is a problem is that he is liked by many girls at school, that makes you have to compete with other girls to win his heart. because you are lazy to compete and make arguments you decide to use a sneaky way to use your black magic

You make a doll that you design to look like her, then you put strands of his hair and sweat into the doll. After finishing, you cast a spell on the doll which allows you to control Nagi's body without him knowing. After school you see Nagi resting. After soccer practice on the outskirts of the field, you intend to test your magic. You slowly rubbed the sensitive part of his body which made him groan in pleasure
