Error Code 404 (Saeran x Reader x Saeyoung) {Completed}

Error Code 404 OVA

(This is what inspired the second half of Error Code 404, hope you enjoy! Also, excuse any grammatical errors, I wrote this about a year ago...)
(This has nothing to do with the actual plot of the story, it's just a little something to show what Error Code 404 originally was)

(Y/n)'s P.O.V.

(1 week ago... I swear in any of you make that joke)

I wandered around the crowded streets, people passing by as I stared down at the sidewalks. My hands were stuffed in my hoodie pocket. My (h/l) (h/c) hair framed my (s/c) face. My (e/c) eyes were dull. I wasn't a very happy go lucky person. I preferred to be alone.

As I walked I felt a vibration coming from my phone which was located inside of my hoodie pocket. I took it out.

R.F.A. Installation Complete

"What the hell?" I muttered to  myself as I looked at the screen. I looked around the streets for somewhere I could stop, only for my eyes to drift to a nearby cafe. I let out a sigh and followed the large crowd of people down the street till I stopped in front of the door to the small shop.

I hopped up the stairs, twisted the door handle, and pulled it, letting out a ring sound as the door opened.

I was hit with the sent of coffee as soon as the door opened up.

I took a step in and sat down by the window before pulling my phone back out.

Weird... I thought, I never downloaded this app. I typed in my password and opened it up.

Hello?

What the hell? I asked myself.

(Y/N)
?

Unknown
can you see this?

(Y/N)
Who is this

Unknown
Finally connected.

Thank god.

It's not every day you get a text from a stranger.
I'm a bit flustered myself. I found a smartphone at the subway station, but all it had was this messenger app.

I want to find the owner, but I don't see any contact info or call records

I've been sending messages with this app but no reply

All I see is an address and some important-looking numbers saved in notes.

I'd like to go there but I'm currently abroad

(Y/n)
first who are you?

Unknown
Me? Oh sorry. I didn't even introduce myself.

I'm just a student studying abroad. I'm Korean.

I could tell you my name, but it doesn't really matter.

You won't find me on search engines ^^;

But, anyways
