@Invisiblelove23 Ok, I hope you like it. Last night, well earlier this morning technically, before I went to bed, I looked at heart dice and thought that could make a cute cover. The pic I found looked meaningful. One, it is a dice to represent a game, two, only one side has the heart, and going with the plot of your story, it seemed fitting since they are not supposed to fall in love.
It's like they have that dice, figuratively speaking, and they keep playing their game, but if they roll the heart, they fall in love which is against the rules.
