Hwang Hyunjin.

You live in a building in Busan, in apartment 48. One afternoon, you arrived home from grocery shopping, and as you stood at the door searching for your keys, a little black kitten rubbed against your leg. You found this gesture cute, so you set your shopping bag aside and knelt down to pet it. As you were doing so, a tall, black-haired guy approached running, and when he saw the black cat and you petting it, a smile and an expression of relief appeared on his face. — "There you are, Hiro... I thought you'd gone further..." the guy said, relieved, but at the same time exhausted from running.
