Normal POV 
It was a sunny day and the box delivery guy just dropped off the boxes that Elizabeth Sensei and Cristina sensei ordered

Elizabeth :"oh the boxes are here what should we do with them ?Cristina ?"

But Cristina sensei was no where to be seen

Elizabeth :"maybe she in the office ?but what am gonna do these boxes "

That's when Natalie and chase walked by

Elizabeth;"oh oh oh you two ya you two can you help me carry these boxes to the principals office "

Chase:"um ok ? But won't we be late for class ?"

Elizabeth:"oh don't worry I'll tell the teacher that you two were helping me Sooo~"

Elizabeth sensei handed two boxes to chase and a bit heavy box to Natalie

Natalie:"oh o-ok"

Elizabeth:"thank you "

So Elizabeth sensei left the room skipping

Chase:"so um lets go I guess "

A few minutes of walking

Chase :"ok i forgot were the principal office was "

Natalie:"w-weird was isn't around here some where I mean last time we went to principals office it was next to this water fountain "

Chase :"ya?weird. Hey Natalie you ok holding that box it looks pretty heavy here let me help"

Natalie:"no no I'm good now let find that off-uffff"

That's when Natalie tripped and the box opened up and the stuff that was in it flu in the air (looks like they forgot the tape)and the stuff landed on them

Chase:"NATALIE!!!you ok I told you I'll carry the box "

Natalie:"eheheheheh sorry"

Chase:"it's fine at least your ok "

Natalie:"•\\\\\\\•"

Chase :"um we need to you know pick up the stuff that flew out of the box"

Natalie:"oh ya ok"

So they started to put the stuff in the box but

Natalie  :"I wonder why Elizabeth sensei and Cristina sensei need this much string I wonder what they use it for ?"

Chase:"I don't know maybe to tie people who don't obey them"

Natalie :"hahaha maybe "

Chase:"oh you got string(red) stuck in your hair here "
Chase reached out to take  the string off of Natalie's hair but that was a bit of a mistake chase he accidentally pulled the string and he didn't realize that string was also wrapped around his ankles and Natalie s left arm which cased them to be a tangled mess

Chase :"sorry I'll try to get us out "
But that cased them to get more tangled up

Natalie :"........"

Chase:"........."
That's when Elizabeth sensei came skipping

Elizabeth:"hey guys i final found I just wanted to s-......Awwwwww 「赤い糸」(akai ito) so cute ship it "

Elizabeth sensei tuck out her phone and tuck a picture of them

Elizabeth:"and send !good luck getting out of this mess I'll just take the rest of the boxes "

Elizabeth sensei left

Natalie:"chase what's 「赤い糸」?"

Chase:"I don't know maybe some kind of string she likes ?"

Natalie:"well let's get out this mess shall we "

Chase :"ya "
