“Write it on the clou-- Yah! I said on the clouds, not on my skin!”   Wherein on your 20th birthday, the name of your soulmate appears on your skin, and if it doesn’t? It just means your soulmate isn’t 20 yet.   Minju turned 20 first, and to Yuri’s relief, she didn’t get her mark yet. Now all that’s left is to wait a few months for her birthday to see if each other’s name appears on their skin.
