Sunlight filtered through the glass roof, making the inside of Lotte World shimmer. While I was standing in line, laughing and chatting with my friends, a familiar color suddenly caught my eye.

"Huh? Isn't that... our school uniform?"

I turned my head to look again, and it really was. In the middle of this unfamiliar amusement park stood a boy wearing a very familiar uniform.

"Hey, should we go talk to him?"

At my friend's playful suggestion, my heart skipped a beat for no reason. Just then, he also raised his head and looked toward us.
