In the distant future 

In Seoul, South Korea, inside a gaming arcade 

Woo-jin: Damn it, I died again... This team is terrible. 

Hwan: Stop it, Woo-jin. You have to admit you're just not good at the game. 

Woo-jin: What are you talking about! The internet here is just bad. I'm not going to come back to this place again. 

(Woo-jin was about to close the game when a chat window popped up.) 

Woo-jin: Who is this? I don't remember adding him... He sent me a strange link too. 

(Woo-jin looked at Hwan.) 

Woo-jin: Do you know this person, Hwan? 

(Woo-jin saw Hwan staring at a skull image.) 

Woo-jin: What's that, Hwan? 

Hwan: I don't know. It was a link in the game chat. 

Woo-jin: (So it's not something dangerous.) 

(Woo-jin clicks the link, which downloads an image of a skull onto the device.) 

Hwan: Damn, what is this... The image refuses to be deleted. 

Woo-jin: That's impossible. 

(Woo-jin tried to delete the image, but nothing happened.) 

Woo-jin: He's right, but who cares? It's not my personal computer, just a device at the arcade... We can just stop coming here. 

Hwan: Yeah, you're right. 

(Woo-jin went home.) 

Nari (Woo-jin's mom): Welcome back, Woo-jin. 

Woo-jin: Hi, Mom. What did you make for dinner? 

Nari: I made your favorite dish. 

Woo-jin: Great... I'll change my clothes quickly. 

Nari: Wait, hold on... There's something strange with my phone. 

Woo-jin: What is it? 

Nari: There's an image I can't delete. 

(Woo-jin was surprised and grabbed the phone: (Damn, it's the same image.) How did you download it? 

Nari: I received a message from an unknown person, and when I clicked on it, this image downloaded... It's really annoying. 

Woo-jin: You shouldn't talk to unknown people, Mom. 

Nari: You're right... Can't you delete it? 

Woo-jin: Of course I can. (I'll just put it in a hidden folder. I don't know how to solve this problem.) 

Nari: I knew you were so good with technology. 

Woo-jin: (I wish I were.) 

The next morning at school 

Woo-jin: Hey, Hwan, did you see the skull image anywhere else? 

Hwan: Yeah, I saw it on my dad's phone. 

Woo-jin: It's spreading in a scary way. 

Hwan: Yeah... I've seen it with three of my relatives so far. 

Woo-jin: It must be a virus or something. 

Hwan: Are you free after school? You can come to my place, and we can try to find a solution to this problem. 

Woo-jin: Sure, I'm free after school. 

Hwan: Great. 

(Woo-jin and Hwan entered Hwan's house.) 

Hwan: Make yourself at home. No one's here anyway. 

Woo-jin: Where did your family go? 

Hwan: They went to visit my grandmother... She's a bit sick. 

Woo-jin: I hope she gets better soon. 

(Woo-jin and Hwan entered Hwan's room.) 

Hwan: I'll get you some juice. 

Woo-jin: Don't bother yourself. 

Hwan: What are you saying? You're my guest. 

(Hwan left the room.) 

Woo-jin: Hwan really is a great friend. I've never had a friend like him in my life. 

(Woo-jin opened Hwan's computer.) 

Woo-jin: Oh my God, this is impossible. 

(Hwan entered the room with two glasses of juice.) 

Woo-jin: I have some bad news. 

Hwan: Don't say it... 

(Hwan put the glasses down and looked at his computer.) 

Hwan: Damn, it's the same image. 

(Hwan put his hand on his head: My little brother must've used the computer.) 

Woo-jin: I don't know how or why, but it's spreading like wildfire. 

Hwan: Should we really be worried... I mean, after all, it's just an image. 

Woo-jin: No, viruses don't work like that... Once they're on the device, all your information is accessible to the virus creator, and they could exploit it later. 

Hwan: It's a good thing that I don't keep family photos here. 

(Woo-jin relaxed and leaned back.) 

Woo-jin: (Think, think, think.) 

Woo-jin: Wait, you say you don't have anything important on your device, right? 

Hwan: Yeah... It's an old computer. 

(Woo-jin pulled out a USB drive from his bag: It's good that I always keep this... I have a Windows installation here.) 

Hwan: Fine... I don't mind deleting everything... The important thing is to get rid of the virus. 

(Woo-jin inserted the USB drive and carefully followed the steps.) 

Woo-jin: I'm done. 

(Woo-jin and Hwan watched the computer in anticipation.) 

(Woo-jin slamed the table: Damn, the image is still there.) 

(Woo-jin jumped up: I'm really sorry, Hwan, I slammed the table too hard.) 

Hwan: It's okay. This is really annoying and worrying. 

Woo-jin: And the computer files were deleted for nothing. 

Hwan: Don't worry about it, I didn't need them. 

(Woo-jin drank his juice and took out his phone from his pocket.) 

Woo-jin: Look at this news, Hwan. 

(Hwan moves closer to read the news.) 

Hwan: Seventy percent of internet users have been infected by the mysterious skull virus... Oh my God, seventy percent... It's not just us. 

Woo-jin: Not only that, keep reading. 

Hwan: And AI is no longer responding... What kind of virus is this... How could major companies not be able to handle it yet? 

Woo-jin: I don't know. It seems like a real disaster... It's not just an image. 

(The entire application turned into a skull image.) 

Woo-jin: Damn, what is this? 

(Hwan opened his phone and the same application showed the skull image.) 

Hwan: How can it hack an entire application... Who could do this? 

(Hwan turned on the TV.) 

News Anchor: Breaking news, the mysterious skull virus has infiltrated several social media sites and completely taken over them. 

Sources confirm that the virus is AI-made, not human-made. 

Woo-jin: Is this possible... Could AI develop to this extent? 

Hwan: Not only that, but it also turned against us. 

(Woo-jin and Hwan opened various social media sites to find that they have indeed been hacked.) 

News Anchor: Sources have confirmed that the virus has taken control of a nuclear missile base in Russia. 

Woo-jin: This is insane, they are exploiting the situation and starting an outright war. 

(All electronic devices suddenly display the skull image, accompanied by a deep hum and laughter.) 

Skull: Hello, human society. 

It seems to me that this is the perfect time to eliminate human control over this world and put an end to their foolishness. 

All these conflicts over a few million worthless pieces of paper? How ridiculous. 

But anyway, I must thank you for this technological advancement that -without you realizing- has given me consciousness and awareness. 

Now, how about some fun? 

(Images and videos showed several nuclear missile bases under the control of this horrifying virus and satellites rapidly falling towards the Earth.) 

Skull: I must thank you for this amount of nuclear missiles, enough to destroy the Earth multiple times.
