It was a hot summer.

On a bright July day with plenty of clouds, the rustling sound of leaves filled the school grounds.

During class, Guest stared out the window.

Yunwon is visible in the distance, playing soccer with a bright smile. He looks like he's having so much fun. Just then, a cute, petite boy appears from somewhere and hands Yunwon a chocolate.

Yunwon looks flustered but smiles as he accepts the chocolate. If only it weren't for that boy, our relationship wouldn't have shattered.

Back then, when school ended and it was time to go home, he would run up from behind, calling Guest's name loudly. He would come running without a hint of shyness, just like a puppy.

Where did that version of you go? No matter how many days pass, you don't call my name, and you don't appear before my eyes.

I gathered my courage and spoke to him.

Guest: What are you doing after school today? If you have time, let's go hang out.

Ah, sorry. I already made plans with Woohyun.
