Start
Tw: mentions of blood, detailed k!lling and swearing

You we're walking in the halls talking to zenitsu about random stuff when tanjiro walke up to you. "Oh hey tajiro!" you gave tanjiro a smile he smiled back. "Hey zenitsu I was wondering would you like to come over to my place tonight along with tanjiro and Inosuke" you asked zenitsu.

" Oh I would love that (M/n)!" zenitsu clapped his hands together and smiled. You guys started to walk out of the school together leaving tanjiro. {Grrrrr zenitsu is taking my precious precious (M/n) away from me.... He wouldn't get in the way if I just...
K!lled him. No tanjiro what are you thinking they are just good friends} tanjiro stared at your slowly fading body figure.

Heart eyes formed on tanjiro and a random person walked past and stared at him. Tanjiro went back to normal and smiled at the man. The man walked off slightly confused.

It was soon time for your little get together. Zenitsu, Inosuke and you were all waiting for tanjiro. While you were waiting you guys were all talking. The doorbell rang and you got up and opened the door and saw tanjiro smiling.

"Hey tanjiro! Come in" you moved aside a bit and he walked in. You closed the door and locked it. (For safety measures). He followed you to the living room. "Hey guys!" tanjiro smiled at inosuke and zenitsu. "Hey tanjiro let's get to playing our games!" zenitsu smiled like a child.

You all agreed and since you have woods behind the house and also since you live in a country with not a lot of people you guys agreed to play hide&seek in the woods. Not a good idea if you ask me.

Tanjiro was it and he started counting. Inosuke was the first to run away and you and zenitsu ran after giggling trying to find a good hiding spot. You found a good spot in the top of very dense tree tops. You could still see down but you weren't going to fall.

It was soon getting dark and you started to get antsy.  Where was tanjiro... Where were your friends.
"(M/n) come out you won!" you heard tanjiro yell from a surprisingly close distant.

You laughed and climbed down the tree. But when you reached the ground a stench came to your nose.

Start of hide&seek
Tanjiro's POV

Where is zenitsu I need to k!ll him first he was the one messing with my (M/n). I found the dude hiding in a pile of leaves. Hehehe what a terrible hiding spot he has.... HAHAHAHA WHAT A LOSER HOW CAN HE EVEN HAVE A CHANCE WITH MY (M/N)! I approached him and i started feeling all tingly. I was going to k!ll him I hade a kn!fe and everything!

Tanjiro jumped into the pile of leaves stabbing the clutter in multiple spots. Zenitsu screamed out in pain and tried to get out of the pile of leaves but tanjiro grabbed a hold of his arm and dragged him out.

"T-TANJIRO LET ME GO" Zenitsu screamed again when the cold Blade ran over his arms. "No you tried to take away my lover" tanjiro laughed. "WHO!" that's when tanjiro snapped and screamed at zenitsu.

"(M/N) THAT'S WHO" tanjiro shoved the kn!fe into zenitsu's stomach. Zenitsu coughed up blood some getting on tanjiro's face. Tanjiro whipped it off with his sleeve. He grabbed the kn!fe a pulled it out. That made it even worse now blood was coming out of his stomach. Tanjiro stared at his friends dying state.

No... They weren't friends anymore there friendship ended when zenitsu became friends with (M/n).
