>>7874862A boy falls in love with a girl.
Unable to confess, he is gifted by a deus ex machina with the girl's phone number. Never minding the strange area 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 a perplexed expression. After some investigation, he finds out that the girl he called is not the same girl he fell in love with. In fact, she doesn't exist in this universe at all. She is the girl's alternate universe counterpart, who has fallen in love with the MC's own AU self, who too is blissfully unaware of her crush.
