A boy falls in love with a girl.
Unable to confess, he is gifted with by a deus ex machina with a soccer phone game with the girl’s contact information. Never minding the strange 'Season 2' label next to her name, he immediately calls her through the app, 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 phone game counterpart, who has fallen in love with the MC’s own AU self, who too is blissfully unaware of her crush.
Hijinks ensue as the two strike up a deal to give each other their darkest, most private secrets in order to equip the other with the crystals they need to draw the heart of their other selves. While the two spend more and more money trying to get their respective loved ones, DRAMA ensues as they begin to fall in love with each other instead and question the NATURE of SPENDING MONEY ON A PHONE GAME IN THE NAME OF ONE'S WAIFU.
