Teasing Gojo is m/n's new hobby

Waking up from that long day we had yesterday, i get up and get ready.
Hearing a buzz from my phone on the bedside table, while I was changing my top, I go and pick it up.
It was a message from....

Gojo's the best?
How did he get my number? Never Mind that, how is that name set already? Did he somehow get into my phone while I was out?
Maybe Yuji gave it to him, though he could have asked if it was okay to or not, sigh, Oh well.
It seems like their was another one sent after I was contemplating my thoughts, I tap the new messages and start reading the contents.

Gojo's the best
Wakey wakey!
Open the door!

M/n
Why do you have my number, you blindfolded weirdo?

————————————————————————————————————————————————————————————————————————————————————
After I sent that I quickly finish getting dressed and grabbed my stuff including my phone, seeing if there's anything else I need.
As I do that I here another buzz from my phone.
————————————————————————————————————————————————————————————————————————————————————

Gojo's the best
Just open the door~!

M/n
No

Gojo's the best
Wait did you just call me a blindfold weirdo?!
How could you!!

M/n
Very easily
Now answer the question

Gojo's the best

Tall white rat

Getting off my phone for now I hear banging on my door, opening it I see Gojo with fake tears running down his face, pouting at me and calling me a meanie.
I only smile, saying this is payback for teasing me, as I walk past him with a happy hum.
Leaving the man to childishly whine while following me to my destination, I wait outside my childhood friend's bedroom door, for him to come out.
Calling and knocking on the door, I hear him quickly shuffling around, soon opening the door to greet me.

"Morning Yuji!" I exclaimed, as i ruffle his hair making it messier than it already was after the rush to get ready.
He joyfully replies back, as we start walking to the kitchen, though Yuji does ask why Gojo's acting like this.

"Well-" I get interrupted before I could explain.
"HE CALLED ME MEAN NAMES!" He yells, practically leaning all his body weight on my poor friend.
Itadori gave me the most disappointed face I could imagine, though I didn't exactly deserve that.
