It was another day at home. Ngoc and Shido were doing homework together.

When they're done, they asked each other at the same time.

Ngoc/Shido: So, what do you want to do?

They surprised about how they talked not only like the other but also at the same time.

Ngoc/Shido: Woah, that's crazy. Man, we've been spending way too much time together. Like damn. Like damn! Damnnnnnnnn!

They started to get annoyed.

Ngoc/Shido: Okay, stop copying me. Stop copying me! Dude, this is kinda freaking me out.

They're starting to freak out.

Ngoc/Shido: Okay, you stop talking and I'll say something.

Ngoc/Shido: ...

Ngoc/Shido: Say something. No, you don't talk, I will! No you, you don't talk! God damn it!

Ngoc/Shido: Okay seriously, what the hell?

Then an idea popped up in their head.

Ngoc/Shido: I got it, say something completely random. Ready? One, two, three, Bananarama! What the fuck?! Why would you think to say that too? It's not even a real word! Okay, let's just not talk.

They stopped talking for twelve seconds and exhaled in between.

Ngoc/Shido: Okay, it's gotta be over now. Shit! I know, let's just, uh, text each other instead.

They said as they picked up their phones. They texted, "Tohka is cute af" and sent it to the other at the same time.

Ngoc/Shido: Why the hell would you say that too?! Okay, this has to stop now! I'm serious, stop! Stop! *talk faster* I'm talking so fast, you can't possibly keep up with what I'm saying! Damn it!

Ngoc/Shido: AAAHHHH! Woof woof! Even animal noises?! God!

Ngoc/Shido: ...

Ngoc/Shido: Meow. Fuck! That's it!

They stood up and went to the living room and got farther apart from each other.

Ngoc/Shido: I'm gonna knock you out so I don't have to hear your stupid voice saying everything I'm saying! Take this!

And then they charged at each other.

Ngoc/Shido: Wait, we're not allowed to fight in the house!

Ngoc stumbled as Shido hit the wall and got knocked out.

Ngoc: Ah, It's finally over.

Out of nowhere, Kaguya entered the scene with her phone on her hand.

Kaguya: Stop right there! Why did you murder him?

Ngoc: You got it all wrong. Something really weird happened and we started saying everything at the same time and it was driving us crazy but, now it's over.

He shaked Kaguya.

Ngoc: It's finally over!

The shake made Kaguya to drop her phone on the ground.

Ngoc/Kaguya: Oh, let me get it.

They bent down to pick up the phone but they bumped each other's heads in progress.

Ngoc/Kaguya: Oh, sorry about that.

And then they realize...

Ngoc/Kaguya: Did you say the same thing I said? It's happening again...!

They fell on their knees before they yelled.

Ngoc/Kaguya: NOOOOOOOOOOOOOOOO!!!!!

Ngoc/Kaguya: *deep breath*

Ngoc/Kaguya: AAAAHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!

And so the talking curse continued for years on end.
(just kidding lol. Don't take this seriously)
