An Earth boy falls in love with a Mewni girl.
Unable to confess, he is gifted with by a magic mirror on the wall with the girl’s mirror phone number. Never minding the strange dimension code, he immediately calls her, and is overjoyed to find out that she has a crush on him as well.
But, the next day, when he recounts the previous day’s confessions to the girl, she only looks at him with an idiotic and perplexed expression. After some investigation, he finds out that the girl he called is not the same blue hair streaked princess he fell in love with. In fact, she doesn’t exist in this universe at all. She is the girl’s alternate universe Mewni counterpart, who has fallen in love with the MC’s own AU bad hellboy self, who too is blissfully unaware of her crush.
It gets a little weird as the two strike up a deal to give each other their darkest, most private secrets in order to equip the other with the magic they need to conquer the heart of their other selves. While the two chase their respective loved ones, DRAMA ensues as they begin to fall in love with each other instead and question the NATURE of LOVE.
