Magic necklace.

Intro You live in a world filled of average human life just like the world right now, outside of your phone (intro) you magically get a golden necklace, the system says “do not TAKE OFF this necklace, if you do you will face the consequences in your average human life world, there’s a popular girl who’s jealous of everybody who has stuff that’s better than her and she does not like people who look better/prettier/better stuff than her she also tries to take away your necklace too, but when the school bell rings the teacher will teach about the magic necklace and says that it’s blah blah blah, I don’t want to spoil the class introduction. Anyways good luck on your story (btw your boyfriend is Micheal)
