In this world, you discover your soulmate once you see their voice. Yes, see because only your soulmates voice has colour with it. 

But Gahyeon is now 21 and she still hasn’t met hers, all her friends have found theirs. But one day she sees it, but she can’t understand the rest. 

-I’m terrible at descriptions but comment any questions. And also the release date is coming soon ;)-
