In a ckmpany drinking party, the uke (who was straight and doesnt look like uke, with a stern face and nice body) just randomly picks up seme and takes him home and they start living together. But one day after buying a stone from a fortune teller, he falls in a puddle and tranferred to a parallel world. In the parallel world uke and seme dont live together, and they figure out how to go back to the normal worlds. They end up dating after things are sorted out
