"(Y/n)......" Matthew sighed.
"Yes, Mattie?"
"Ivan sat on me again today..."
"It's okay, Mattie. Though they don't notice you, it's okay because I can see you." You patted his head.
"Thank you, (y/n)..."
---------------------------------------
Mattie is invisible. He's not a ghost, but he's practically invisible. If people can see him, they will mistake him for Alfred. Even Alfred, his own brother, did not notice him. The only one who can notice him is you. Francis used to notice him, but he just left him.
So now it's just you.
For a while, you've been having this little crush on him.
You've always loved his cute and shy personality,
But
.
.
.
Can you accept his yandere side?
----------------------------------
Timeskip, World Meeting

"So, let's move on to the next problem." Germany tidied his papers and cleared his throat.
"Umm..."
"What's the next problem, Alfred?"
"Hey...."
"The world financial crisis, duude!!" Alfred replied with his usual energetic reply.
"Alfred...."

Mattie <tried> to get everyone's attention, but failed miserably. You noticed that and you tried to defend him.

"EVERYONE!!!!" As you said that everyone's head turned to you.
"(Y/n)?!?!" Mattie gasped.
"MATTIE HAS TRIED TO GRAB YOUR ATTENTION BUT YOU KEPT IGNORING HIM!!!!!!!!! FOR ONCE, PLEASE NOTICE HIM!!!!! HE HAS SUFFERED ENOUGH!!!!!" You shouted at the top of your lungs.
"Who's---"
"HE'S YOUR FRIGGIN BROTHER, ALFRED!!!! IT'S BECAUSE OF YOU PEOPLE MISTAKE HIM FOR YOU!!!!"
The whole meeting room is covered in silence.
"Ahem. Miss (y/n), please do not shout. Alright, we will listen to what Matthew has to say."
"......." Mattie was flustered.
"Well, Mattie? You can speak now." You smiled warmly at him.
"Thank you." He smiled back.

"I will do better things for you after this." He smirked evilly, his voice barely audible.

-----------------------------------
Back to the world meeting~~~

You headed to the meeting room to find your crush, Mattie. But he wasn't there.
Instead there were

Corpses of the other countries lying in the ground.

You gasped in shock.
"W-W-Who did this?!?!?!?"
"I did, (y/n)~"

It was Mattie. Covered in blood. He was holding Kumajiro's head.
He also killed him.

"You.... Killed.... Kumajiro... And the others....." You were speechless.
You hadn't expected this to happen.
Your shy and cute crush, Mattie...
Killed all of them?!?!?!?!?

"I wanted to make the world that only consisted two of us, (y/n). (Kira reference lol) That way, only you could notice me."

"That's......" Your face turned pale, you were speechless.

Your lips curled into a smile.
"Thank you, Mattie."
