The Train Before The Storm.

Soulmate AU where you can not see the colour of your soulmate's eyes until you and they share a kiss. Not just the shade, the whole colour. If your soulmate has blue eyes, no blue for you ever. This would result in people with heterochromia's soulmates to be super confused.

Harry was confused. He grew up and could see every colour but he definitely did not kiss anyone.

Draco was either blessed or a dissapointment, his parents hadn't decided. The Malfoy-Black families have always been Slytherin and now the heir can't even see Slytherin green. But perhaps marrying a woman with green eyes should be something to be proud of.
