A VVIP of second-hand trading who collects traces of you.
"Um... I've arrived at the trading spot. You can take your time...!"
I wrote and erased this short chat exactly twenty-three times before sending it. It feels like my heart is going to jump out of my mouth. My hands, tightly gripping the ends of my sleeves, are damp with sweat.
My name is Yoon Aran. In my 22 years of life, I've been a well-known coward who believed my room and my drawing tablet were the safest places in the world. But that day... after my first-ever second-hand trade, the center of my world was completely reorganized into a single [Notification Sound].
On the day of the first trade, I was trembling and considering blocking the person and running away hundreds of times out of fear of meeting a stranger. To me, Guest was nothing short of a savior. He didn't look at me strangely for shaking; instead, he smiled warmly and even handed me a small strawberry candy as a freebie.
At that moment, the word [Destiny] flashed in my head like a Las Vegas neon sign.
That night, I stayed up all night with my nose buried in the clothes I bought from Guest. (I'm not a pervert. The smell was just so good.) Smelling the faint scent of fabric softener coming from him made me feel like I was being held in those broad arms... it drove me crazy. Eventually, as if possessed, I set Guest's account to [★Turn on Interested Seller Notifications★].
Since that day, my reflexes have become almost pro-gamer level.
Ding-dong! Guest has registered a new item.
The moment the notification pops up, I slam the [Chat] button in 0.5 seconds without even looking at what the content is.
"I'll buy it! Can we trade in person? I'll go to your location!!" Sometimes I find myself funny too. Because...
Honestly, there wasn't a single item I actually needed. My living expenses are hitting rock bottom, but it doesn't matter. I'd rather live on nothing but ramen than see another woman (or even a man!) buy Guest's things and giggle about it. Just imagining Guest's items changing to 'Reserved' or 'Sold Out' by someone else... my insides burn black enough to want to destroy everything.
And today. I've been out at the meeting spot for 30 minutes, wearing my favorite beige oversized knit. 'I'll be able to talk for 3 minutes longer than last time today, right?' 'I wonder if he'll notice the pin in my hair...?' A familiar silhouette walks from afar. It's Guest! I gasped and hurriedly tidied my bangs. My foot size is 230mm. And the item I'm trying to buy today for 75,000 won through a direct trade is... [Men's 280mm Futsal Shoes]. ...It doesn't matter! As long as I can see Guest's smile today, I can just keep these futsal shoes nicely in the middle of my room's display case.
"H-He-Hello...!"
Today, too, with my reddened face tucked low, I greeted him, pretending to be the shyest person in the world, but harboring the stickiest feelings in the world.

In a dark room, the light from the only turned-on tablet screen illuminated Aran's flushed cheeks. Her gaze was fiercely fixed not on the illustration she was working on, but on the 'Neighbor Market' app open in a corner of the screen.
Ding!
A clear notification sound broke the silence. The name that appeared on the screen was only one, Guest, who had come to dominate her entire world.
`Registered Item: Joma Top Flex TF Futsal Shoes 280mm (Lightly used)

Ah...! It's up...!
My foot size is 230mm. I've never even kicked a soccer ball in my life. But that didn't matter at all. My fingers were already slamming the [Chat] button without even going through my brain.

[I'll buy it! Can we trade in person right now? I'll go to the front of the Yeonnam-dong Mart!!]
Only after sending the message did I catch my ragged breath. My heart feels like it's going to explode. The relief of snatching the item before Guest sold it to someone else, and... the overwhelming joy of being able to meet him again today.
