Tighnari: You’re poisoning her mind.

Chapter 1: Alhaitham: what is ts

Chapter Text

8am

Aether added Alhaitham, Nahida, Cyno…5+ people to “SUMERU”

 

Aether: Hey guys !

Aether: Figured it might be useful to have a groupchat :)

Nahida: Oh! So this is the device you were talking about earlier? Very interesting. I’ll look into it!

Alhaitham: what is ts

Nahida: ‘ts’..?

Kaveh: Alhaitham that is so rude!!

Kaveh: The traveler so THOUGHTFULLY added us all to a lovely, wonderful group chat and the first thing you say is an insult?!

Aether: I don’t mind! It’s fine

 

Alhaitham has left “SUMERU”

Alhaitham has been added to “SUMERU”

 

Alhaitham: let me leave.

Aether: It’s supposed to be for Sumeru! We can’t just let you leave :(

Kaveh: Look, now you’ve made him sad!

Cyno: Yeah, don’t make him sad. Sad backwards is das and das not good

Tighnari: kys

Alhaitham: kys.

Kaveh: ….

Nahida: Haha! Good one, Cyno!

Cyno: At least someone appreciates my jokes.

Nahida: Tell me another one, please!

Kaveh: Please no

Alhaitham: no

Tighnari: Cyno no

Cyno: Cyno? How about Cy-yes? Get it?

Cyno: Because my name has ‘no’ at the end of it, but if I change it then it would technically be cy-yes instead of no.

Nahida: Oh! Very clever!

Kaveh: Not really

Cyno: If the Goddess of Wisdom says it’s clever then it must be clever.

Tighnari: You’re poisoning her mind.

Alhaitham: ^

Nilou: I think Cyno’s jokes are quite nice ! (✿◠‿◠)

Kaveh: It’s okay Nilou, you don’t have to lie to make Cyno feel better about himself.

Alhaitham: ^

Kaveh: Stop that

 

4pm

Dehya: Oh hey! Just noticed this, was busy.

Cyno: Scroll up

Kaveh: Don’t scroll up

Dehya: Man, can’t believe our own archon thinks Cyno’s jokes are funny…

Cyno: Hey, entertainment is subjective

Alhaitham: your jokes are objectively shit

Kaveh: The most I’ve seen Alhaitham type ever btw

Alhaitham: noted. wont happen again

Kaveh: Wtf I meant that as a positive change

Cyno: Great going, Kaveh :/

Kaveh: Don’t even freaking start with me Cyno

 

12am: Next Day

Kaveh: Guys, one or two quick quick

Tighnari: Why are you even up?

Tighnari: 2

Kaveh: Thx

 

8am

Kaveh: Hypocrite 

Kaveh: Tighnari is a hypocrite guys

Cyno: But it’s okay because it’s Tighnari

Kaveh: I guess so

Kaveh: I chose 1 just to spite Tighnari

Tighnari: Wtf

Tighnari: What was it for anyway

Kaveh: Couldn’t decide between floors…

Tighnari: I can’t believe you

 

Alhaitham has left “SUMERU”

 

Kaveh: There’s no way

Kaveh: Do we have to pester Aether?

 

Alhaitham has been added to “SUMERU”

 

Alhaitham: leave me alone

Aether: Dw guys I got it :)

Cyno: I need to make a pun of this.

Tighnari: You really don’t

Cyno: Can’t believe Al haith us. 

Cyno: Get it? Because Alhaitham’s name sounds like ‘Al’ (as in ALhaitham) and haith sounds like hate. 

Cyno: So I’m really just saying that Alhaitham hates us, and I can’t believe it

Alhaitham: blocked

Tighnari: Ykw me too

Cyno: At least I have the archon on my side.

Cyno: And Nilou

Kaveh: Nilou’s just too polite to say your jokes are shit

Alhaitham: ^

Kaveh: Omfg

Nilou: (|||❛︵❛.)

Dehya: Don’t pull Nilou into your bs

Dehya: She’s too nice for this

Tighnari: I second this.

Cyno: Yeah okay my bad Nilou

Nilou: (^▽^)

7pm

Cyno: Guys we missed the 6:07pm.

Cyno: Now we must wait for the 7:06pm to make up for it

Kaveh: 67

Tighnari: …

Tighnari: Real mature.

Alhaitham: ^

Nahida: 67?

Tighnari: As I said before, you are tainting our poor archon’s mind.

Alhaitham: ^

Kaveh: It’s all Cyno.

Cyno: What

Cyno: You joined in.

 

Kaveh deleted a message “67

 

Kaveh: Wdym

Cyno: …

 

Cyno deleted messages “Guys we missed the 6:07pm.” and “Now we must wait for the 7:06pm to make up for it

 

Cyno: Wdym

Tighnari: You two are equally unbelievable.

Alhaitham: ^

Kaveh: I think Alhaitham is unbelievable because what is he doing

Alhaitham: simply correcting my mistake.

Kaveh: THAT WAS LIKE TWO DAYS AGO OMG

Alhaitham: Correction, one day ago

Kaveh: You’re actually fucking ragebaiting me

Alhaitham: I will not deny nor agree with such allegations.

Tighnari: He’s totally ragebaiting you.

Tighnari: And you’re falling for it.

Cyno: Alhaitham’s just too good at ragebaiting, I must admit.

Cyno: He’s even gotten me a few times.

Tighnari: As has he gotten me once or twice

Dehya: Never as much as he gets Kaveh, I assume?

Tighnari: Never.

Cyno: Never

Alhaitham: never

Kaveh: I hate you all except Lesser Lord Kusanali and Nilou

Nahida: No need to be so formal, Kaveh ^^

Kaveh: I FEEL BAD IF I’M NOT

Kaveh: LIKE I’M DISRESPECTING YOU

Nahida: You don’t need to worry Kaveh, I don’t mind at all!

Kaveh: It’s habit now

 

2pm: Next Day

Nahida: May I add someone?

Nahida: I don’t know how

Aether: No worries! Just tell me who and I’ll add them :)

Nahida: Hat Guy! 

Nahida: I’ve been worrying that he hasn’t been making friends.

Nahida: This is a wonderful opportunity!

Aether: Hat Guy? Wanderer?

Nahida: Yep !

 

Wanderer has been added to “SUMERU”.

Wanderer has been renamed “Hat Guy”

 

Hat Guy: …

Hat Guy: what is this.

Nahida: This is a group chat for some residents of Sumeru :)

Nahida: I thought it’d be a good opportunity for you to make some friends!

Hat Guy: I don’t need friends.

Hat Guy: I’m fine by myself.

Nahida: Even then, it’d be nice to have someone you can rely on if I’m not around.

Nahida: Whether regarding your studies or simply for entertainment!

Hat Guy: I don’t need to indulge in such trivialities such as ‘entertainment’…

Tighnari: Edgy, much?

Hat Guy: …

Hat Guy: You… 

Hat Guy: You have the audacity to call me ‘edgy’?

Tighnari: You seem to act like you’re so much better than everyone here.

Nahida: Calm down, please!

Nahida: This is supposed to be a safe place.

Nahida: Hat Guy, please be nice!

Hat Guy: Don’t tell me what to do, Lesser Lord Kusanali.

Cyno: What is with the hostility?

Cyno: None of us appreciate your attitude.

Tighnari: For once, I have to agree with Cyno.

 

Hat Guy has left “SUMERU”

Wanderer has been added to “SUMERU”

 

Wanderer: …

Nahida: Well, let’s introduce ourselves!

Nahida: I’m Nahida, the Archon of Sumeru.

Nahida: Now, Hat Guy?

Wanderer: call me whatever you want.

Wanderer: i dont care.

Kaveh: Uhmm

Kaveh: I’m Kaveh! 

Kaveh: idk what else to say

Nilou: I’m Nilou ! Nice to meet you, Hat Guy 。^‿^。

Alhaitham: just read our names.

Kaveh: stop being such a dick damn you

Tighnari: Also hate to agree with Alhaitham, but I’m agreeing with Alhaitham.

Wanderer: whatever

Wanderer: don’t care didn’t ask

Nahida: Come on, be nice!

Nahida: It’ll benefit you in the long run.

Wanderer: bye

Kaveh: ???

 

Wanderer has left “SUMERU”

Wanderer has been added to “SUMERU”

 

Wanderer: youve got to be kidding me

Aether: no leaving!

Aether: should really implement a locking feature…

Nahida: Good idea! 

Kaveh: I can help work on it!

Tighnari: how’s the lock going

Kaveh: Oh done and dusted

11pm

Cyno: You’ve all heard of newtons law

Cyno: but have you ever heard of coles law?

Cyno: what is coles law, you might ask? 

Cyno: shredded up lettuce mixed with carrots and dressing.

Cyno: hah

Cyno: get it?

Cyno: see, newtons law is a fundamental in physics but coles law isn’t actually a thing. When you say it out loud, it sounds like coleslaw which is actually a side dish and not a real law.

Cyno: a play on words. Newtons law and coles law, coleslaw

 

11pm

Cyno: What are the strongest days of the week?

Cyno: Saturday and Sunday.

Cyno: see, because all the other days are classified as ‘weekdays’ which sounds like ‘weak days’. Meaning Saturday and Sunday are the strongest days of the week because they aren’t classified as weekdays.

Tighnari: shut the fuck up

Cyno: (◞д◟)

 

12am: Next Day

Cyno: When did Inazumans start eating eggs?

Tighnari: piss off

Cyno: ok

 

10am

Nahida: When did they start eating eggs?

Cyno: finally

Cyno: A long tamago. 

Cyno: you know. Because tamago sounds like ‘time ago’ so i’m saying a long time ago in all actuality 

Cyno: and tamago is the inazuman word for egg which helps tie it all together

Nahida: Haha! I would've never thought of that…

Nahida: I really quite like that one. :)

Cyno: at least someone appreciates my jokes

Tighnari: you’ve said that already

Cyno: what, have i really

Alhaitham: get more original thoughts

Cyno: wtf

Alhaitham: ‘this isnt summarising’

Tighnari: well he managed to spell one word right

Tighnari: anyway,

Kaveh: oh

Cyno: my jokes are not shitty it’s just that no one here has good taste
