Carousel of chaos (Jevil x GN.reader)

You never have been verry popular around others,you were a bit weird as some people said because you were a bit shy.Since no children came to be your friend,you started to feel lonely...But one day,as you were at the house of your grandmother during the summer holidays,you found a weird object in the attic,it had a lot of dust on it,when you dusted it,it turned out to be a little clown box.You were curious about it because of the little card symbols on it,a heart,a club,a diamond,a spade and a little joker on the middle.You oppened it and something jumped out of it....or should i say....someone..
