Mystic Messenger X Reader

The phone rang from the bedside table of a girl fast asleep. She didn't stir, but the voicemail picked up, and a boy's voice echoed faintly through the quiet room.

Unknown: "Hi. It's been nice to get in touch with you. With this, please enjoy. I'll be watching over you from where I am. Please be careful... and enjoy the adventure."

The call ended abruptly, leaving only silence.

It was just another ordinary day for (your name here). Living alone had taught you independence, the kind that made solitude feel natural. Your hair was messy, but it caught the sunlight streaming through the window, glowing like a halo. It was Sunday, and you had no plans — no obligations, no noise. Just you.

Yawning, you stretched your limbs and climbed out of bed. As you stood, you picked up your phone, only to notice a strange, unfamiliar icon glowing on the screen. Curiosity tugged at you. You tapped it.

Suddenly, the phone went black. A golden logo appeared: RFA, elegant and ornate. Then, the screen shifted to a blank white background, green letters flashing rapidly across it.

Welcome to RFA.

Your heart raced. Nervous, you pulled the battery out of your phone, forcing it to shut down. Shaken, you decided to ignore it for now — a bath, breakfast, something normal to ground yourself. You left the phone on your bed and went downstairs.

But upstairs, the device flickered back to life. The green lights continued, lines of code crawling across the screen.

After breakfast, you returned to your room. The phone was still glowing. On the screen: RFA. Beneath it, a list of chats, calls, and names you didn't recognize. Against your better judgment, you clicked one.

A chatroom opened. Messages flew by, fast and chaotic.

You: "hEllo?"

707: "Who? WHAT? HACKEEERRRRRRRRRRRR!"
Jumin: "Who are you, and why are you here?"
Zen: "Oh my gosh, how on earth are you in this chat?"
707: "Tracing the IP now... it's coming from Rika's apartment."
Yoosung: "Who are you? What are you doing in Rika's apartment?"
You: "Umm... Rika? I'm at my place."
Yoosung: "Liarrrrr."
707: "No, I'm sure. The IP is from Rika's house."
Jumin: "Miss, can you tell us who you are and how you got here?"
707: "I'm calling V." [Logged out]

You typed nervously: "I don't know. I just woke up with weird flashing green lights on my phone."

Jaehee: "Please, everyone, calm down."
Yoosung: "How can we calm down if someone's in Rika's house?"
Jumin: "Yoosung, please. Calm down."
Zen: "Yeah, the poor girl might be shocked."

You hesitated, then logged out.

Yoosung: "She's escaping!"
Jumin: "Because you scared her."
Zen: "How cruel, Yoosung."

On your side, you muttered: "What the hell was that? How did I end up in that chat?" Frustrated, you tossed your phone aside.

But before you could leave the house, the phone rang again. Against your instincts, you answered.

You: "Hello?"

A boy's voice replied.

707: "Hey. I just saw your pictures. You're pretty cute."

Your stomach dropped.

You: "What? Who are you?"

707: "Oh yeah, I was in the chat earlier."

Panicked, you hung up immediately. Seconds later, a message appeared.

707: "I have all your information. Don't even think about running away — I can track you anywhere you go. This is a warning, so you don't make the wrong decisions. We'll get back to you."

You stared at the screen, frozen. A sigh escaped your lips.

"Why me...?"
