His Protector (Highschool! Karamatsu x Tomboy! reader)

For MatryoshkaVerde

I was walking beside my best friend Karamatsu Matsuno as we walk to class. We have been friends for years. Since childhood to be exact. And don't get me wrong I got along well with all his brothers and his parents, but I was just closer with him. Hence why I'm basically his protector. His bodyguard. Why was I protecting him?

Because he was just so shy and way to pure for this world that's why!

Mostly the shy part though. He can't really stand up for himself so I help him. It's just small stuff though like making sure bullies steer clear and making sure people don't take advantage of him and his timid nature. He was super embarrassed when I first started doing this but was very appreciative of it later on.

We enter class and notice that everyone was talking among themselves. So we went to our desks, right next to each other of course. When I sat down on the table I fiddled with my pants as they had ride up on me. Yes I was wearing pants instead of the uniform skirt. Don't judge me. I don't like skirts or dresses at all and I've been that way since I was little.

"Did you get the homework Karamatsu?" I ask and he blushed softly "well there was one problem I didn't know." He says with a nervous smile and I smile before standing beside him. "Then let me help you." I say and he nods pulling the assignment from his bag. As he did that I got a light punch on my shoulder. I turn my head to see Osomatsu "morning y/n. I see your helping my baby brother again."

I nod and turn to look at the problem Karamatsu had trouble with. After glancing it over I help him put the correct answer. I smile and hug him. "There you go Karamatsu. Now you got it." He smiles shyly and laughs softly

"yeah thanks y/n."
....

I was rushing to get to Karamatsu for lunch. We had separate classes before we had lunch so I was hurrying to the room where his class was. Until this girl calls my attention. "Hey y/n!" I stop and turn to her with an anxious look. "What?" I ask glancing down the hall. "What's the rush?" I hum and turn to look at her. She smirks before looking at me.

"Going to meet up with your boyfriend?"

I blush and my eyes widen. "I don't have a boyfriend and you know that." I say and she laugh softly "honey, yes you kind of do. You just don't realize it." I roll my eyes and turn to leave "just think about it." She says before walking the opposite way. I rush down the hall and saw Karamatsu waiting patiently outside the class.

"Karamatsu!" I say happily while waving my hand. He turns to me with a shy smile. He walks over and we met in the middle before walking to lunch together.

I don't know what that girl was talking about but whatever.
....

I had missed half of the school day because of a doctors appointment. When I walk out of the school office I kept rehearsing my apology to Karamatsu. I took notice that it was lunch and went to find him. As I was walking down the hall I heard someone get slammed against the wall. I hum and round the corner only for my heart to drop.

Karamatsu had been pushed against the wall by another student who I knew as Karma. Karamatsu slid down the wall, pain evident on his face. My face became dark as my protective instinct kicks in full drive. I sped over with a growl "OI! What do you think you are doing?!" I step between the two and shove Karma back. I stood in front of Karamatsu, shielding him.

"Well look who it is. Hello y/n." He says with a smirk and I glare at him. I glance back at Karamatsu who was looking up at me with a surprised look on his face. "You okay Kara?" I ask and Karma laughs. I whip my head around with a scowl. "Seriously Karamatsu you going to let this girl protect you? That's pretty pathetic." I hear Karamatsu whine softly and saw him drop his head down.
