Jongin has a theory about his identifying feature.

Whatever is written on his body will show up on his soulmate’s and vice versa.

It’s the only logical reason he’d have shopping lists and bullet points going down the inside of his forearm and on the back of his hand. Because he knows he didn’t write them.

From this theory, he theorizes about his soulmate themselves.

First, they’re forgetful. They carry a pen or marker but no paper.

Second, they work with flowers. Lists of vases, ribbons, and wire all point to a florist.

Third, they’re right-handed. Anything on his left arm and hand are relatively neat and legible, but anything on his right are deliberate and squiggly.

Fourth, they have no idea what their identifying feature means.
