Giyuu and you had been friends for a while now and it was without a doubt the best time you've ever had. Even though he was silent he always listened to how you would rant about different subjects, today being nothing but that.

As you and Giyuu sat at the lunch table it was time for your daily ramble. "Can you believe that mechi bit me today!" you say pointing at the bite mark made by your dog, mechi. "I was just trying to pet he then she turned around and chomp! Just like that! There was even a slight but of blood!" you finished shoving some food into your mouth.

Giyuu stared at you nodding. "And then my mom fricken yelled at me because of the dog bite! "Oh you shouldn't have riled her up!" like ma I didn't rile her up she just bit me!" giyuu nodded again as you took another bite of your burger.

"Damn this burger is good" you said eating the last of the burger. "You do love Mechi still... Right?" you looked up and nodded at Giyuu's question. "Of course I still love her! It was only one little bite!" Giyuu nodded disappointed that he can't get rid of the dog.

"Hey hey hey!" you both looked up and saw a new kid looking eager. "Umm hi?" you said putting down your drink. "I was wondering if I could sit with you both since I'm new here and I wanted to get to know some people!" you and giyuu looked at eachother before you both came up with different answers.

"Sure!" "no" the new kid stared at the both of you in confusion. "Is that a yes... Or a no..." you looked at giyuu and cocked your eyebrow. He stared at you and your eyes dropped slightly before turning up.

"No you can sit with us! Just pull up a chair!" you said patting the spot next to you. Giyuu looked at you in betrayal. "Great!" he set down his stuff before walking off to grab a chair.

"Y/n! You know how nervous I get around new people!" giyuu said gripping his fork with gorilla strength. "Ok listen.. -holds your face with you fingers- you need more friends that aren't me, Sabito and Makomo" you said bringing down your fingers and pointing at him.

He deadpanned. "Wait where even are Sabito and Makomo?" "They aren't here today because they left to go to a concert.. I think..Idk" you nodded as the kid pulled up a chair and set right next to you.

"So what made you decide to join this school?" you asked taking another bite of your food. "Well my parents wanted me to have a better life so they sent me hear! Well to live with my aunt and get a good scholarship!" he said taking a bite of his food.

Giyuu just sat there silently glaring at the boy as his grip on the spoon tightened. This continued as the new boy, Marcus, decided that you guys were now his besties and would do whatever he says.

So now you're all sitting here couple year's later now an upperclassmen in kimetsu academy. Marcus always loved to boss giyuu around to get him to do whatever he wanted and giyuu had to do it because you were there.

Sabito and Makomo were back and they quickly caught onto what was happening. They thought you didn't know so they tried to stop Marcus by themselves but it didn't work.

You weren't oblivious to it. You knew what Marcus was doing and you hated it. You would always try to bring it up to Marcus but he brushed it aside. So now you're starting to hate Marcus alot.

So here we are the group all sitting on a park bench while Marcus blabbered about how he's so nice and how life's going great for him. "That's great Marcus" you said with sarcasm while resting your head on your hand.

"Ikr! And you could make my life even better!" he exclaimed looking at you intently. "I'm sorry what" you asked lifting your head off of your hand. "What I'm saying is that me and you should date!"
