Beerus falls in love with Goku.
Unable to confess, he is gifted by a deus ex machina (Whis) with the Saiyan's phone number. Never minding the strange area code, he immediately calls him, and is overjoyed to find out that he has a crush on him as well.
But, the next day, when Beerus recounts the previous day's confessions to Goku, he only looks at him with a perplexed expression. After some investigation, he finds out that the Saiyan he called is not the same Saiyan he fell in love with. In fact, he doesn't exist in this universe at all. He is Kakarrot's alternate universe counterpart, who has fallen in love with the God of Destruction's own AU self, who too is blissfully unaware of his 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 weapons 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 CHAOS.
