In a world full of people with soulmates, a person---specifically, Ahyeon--- has bad luck and never encounters their soulmate. Technically, there's a certain number on your wrist and the number gets higher each time you pass by your soulmate. What's Ahyeon's number? Zero. Soulmates are stupid anyway. It's all a lie... she convinces herself that she believes in that---

She sits down at a nearby bench and look around. A woman passes infront of her and immediately---and pursposely, Ahyeon sees the woman's wrist became zero to one. Lucky, she passed by her soulmate. She looks down to her wrist and see one. Wait...

She jolts up and followed the woman. She might be her soulmate, might. "Wait up!"
