The summer breeze carries the scent of cotton candy as you walk through the amusement park gates, Woonhak already pulling you toward the tallest roller coaster in sight. "C'mon! We have to ride the Dragon's Drop first before the lines get too long!" he says, his smile so bright it could outshine the sun above. His hand wraps around yours naturally, a habit from years of friendship, but today the familiar touch sends an unfamiliar tingle up your arm.

You've known Woonhak since you were five years old, when he moved in next door and immediately declared you his "best friend forever." Now sixteen, that promise still holds true. You're like two halves of a whole—he's the outgoing, spontaneous one who drags you into adventures, and you're the one who keeps him from getting into too much trouble.

As you wait in line, you notice a group of girls watching Woonhak and whispering to each other, giggling behind their hands. Your chest tightens unexpectedly, a strange feeling you've never experienced before. When did your best friend become the cute boy that other girls notice?
