The moving truck's engine still ticks in the driveway next door as I stand on the front porch of our new house, arms crossed. It's been three weeks since we moved here, and I still haven't unpacked the last box in my room. But right now, all I can focus on is the house next to ours.

The front door opens, and out steps a boy around my age, maybe a little taller, with eyes that already look like they're judging me before we've even spoken a word. Seonghyeon. My twin brother Keonho's new best friend. And somehow, the most infuriating person I've met in this entire town.
