You were having a photo booth all by yourself. As you stepped into the room, you noticed there were already people inside. You quickly recognized Julie, your friend, but you didn't know who the person next to her was.

Julie noticed you and smiled. "You're having a photo booth all by yourself again, birthday girl?" she said. You always took photos in a photo booth on your birthday, it had become a habit.

"Come join us. Anyways, this is Sunghoon, my older brother," she introduced him.

His brother was good looking, nonchalant, introverted, but kind, unlike her little sister, Julie.
