If you don't get what the (Male) in the title means, go read the introduction. 

Before the killing school trip

You were taking a typical walk, as you habitually do. While doing so, a woman dropped her groceries, and you responded by helping.

You

"Are you alright?"

Woman

"Y-Yes, thank you very much."

You sighed and proceeded walking. Right as you did, you heard the woman fall again.

You

"Here, I can help you."

Woman

"What a generous boy you are... Thank you again."

You took her surprisingly heavy grocery bags and walked her home. 

You

"I guess I should get going now."

Woman

"Ah, I'd like you to meet my son."

You

Oh great...

Woman

"Teruteru!"

Teruteru

"What is it, mama?"

He swiftly regarded you at the door, then got rid of his accent. It was like he was a new person.

Teruteru

"I-I mean mom- mother... Wh-What is it mother?"

Woman

"I'd like you to meet... Sorry, what's your name?"

She tensely laughed.

You

"My name is Y/N."

Woman

"Ah! I'd like you to meet Y/N. This is the nice boy that brought me back home safely."

Teruteru

"Wait, you collapsed again?!"

Woman

"Well, yes, but Y/N helped me get home. Without him, I would've had to come home very late."

Teruteru

"M-Mother, how about I get groceries for the family now? This is putting you through so much trouble..."

You

"Hey, I can get the groceries for your family if you'd like. I'm not busy at all."

Teruteru's mother

"Oh! That would be so kind! Thank you very much!"

It was essentially like she was glorifying you like a God, bowing continuously.

You

"Hehe, it's not a big deal."

Teruteru looked quite unsettled, more like jealous. But you questioned what he could've been skeptical of.

And so, for several weeks, you brought the groceries for Teruteru's family. Sometimes you were permitted to stay at their home and you could taste the delightful food made by Teruteru.

You

"This is really good! Teruteru, did you hear what I said?! It's really good!"

Teruteru

"Yes yes... I can hear you!"

You

"Come on, you've never played one before?"

You asked. You'd just brought Teruteru to your home, requesting him to play video games with you.

Teruteru

"Well I was always concentrated on other things but... These video games look quite cool."

You

"Hell yeah! They're super cool!"

You and he stayed up all night, it took you so much time to teach Teruteru how to control a game controller.

During the killing school trip

You

"Wow... Teruteru, I didn't know that your dishes were this good."

Teruteru

"Huh?! So you underestimate me?!"

You

"Well- Not exactly but..."

Teruteru sighed.

Teruteru

"It's okay. You probably said that because of the way I act, right? Well, I can't help it. It's not my fault."

Hiyoko

"Huh?! A fat disgusting tiny little pig like you can't help that your a perv?! It's that simple! Just stop making us girls feel uncomfortable!"

You

"Hey, Hiyoko!"

Hiyoko

"Whaaat?! I'm just giving him some tips!"

You

"Well don't say it like that! You'll make him upset!"

You then discerned that everyone else wasn't on your side.

You

"Wow... You guys really hate Teruteru that much?"

They all kept silent.

You

"He makes such great meals for you, and you treat him like that?"

Hajime

"No Y/N you don't get it-"

You

"No, I'm pretty sure I do, Hajime."

You said Hajime's name in a distinctive tone.

Teruteru exited the restaurant, and you chased after him.

Hiyoko

"Ew! Does he really have a crush on a sickening pervert?!"

You

"Teruteru! Please open the door!"

Teruteru

"Why do you want to see me? It's not like there's anything to see here. You're just going to see my disgusting face after all."

You

"Hey! You shouldn't listen to them, okay?!"

Teruteru

"Why shouldn't I? People say stuff like that about me all the time. I'm pretty much forced to listen to it."

There was a short stillness.

You

"I don't think badly of you."

Teruteru

"..."

When you didn't hear an answer, you assumed he'd be neglecting you permanently and started making your way back to the restaurant.

Teruteru

"You don't?"

You glanced back at his cottage.

You

"Yeah! I'd never say anything bad about you! You shouldn't listen to those idiots. They're all idiots! If you want, when we get out of this horrible place filled with idiots, can you teach me how to cook?"

Teruteru

"Me? Teach you? How to cook? I'd love to!"

Even though you'd regularly be made fun of for hanging around with Teruteru, Teruteru was glad that he had a good friend and treated him impartially.
