My little sister is too cute, so I have to protect her!

As I ran towards the school, many people looked at us with curious eyes. It was as if they were all looking at some kind of strange creature, but I couldn't care less. Mio's a lot more important than the opinion of other people.

When I reached the school grounds, I immediately ran towards the infirmary.

"Is anyone here?", I said that as I kicked the door open.

"WHO DISTURBED MY SLEE-, Oh, it's just the Miyamura siblings, huh? So, what happened again, Miyamura-kun?", asked the nurse.

"M-My sister! She suddenly bled a lot from her nose! What should I do?!?!"

As I placed Mio down on one of the infirmary's bed, I heard her mumble something.

"Heh-heh-heh... I can finally die in peace... It's a pleasure to die in your arms... Nii-sama... May we be husband and wife in our next life..."

"No!!! Mio!!! Don't die on me!!!", I cried out in grief. M-My cute little sister... Is she going to die just like this? M-maybe I'll just die with her right here...

As I was having that thought, the nurse chopped both of our head and said,

"Hey, you guys. It's just a little nosebleed. And can't you get used to it already?!?! I saw you running up to me like this at least twice a week!"

For some reason that I can't seem to understand, she said that with a tired look on her face.

"Thank you! Koyuki-san! You're our saviour!", I thanked her from the bottom of my heart.

"Why do I have to see a lovebird's display of affection so early in the morning?!?!"

"M-Me and nii-sama... lovers?!?! Heh-heh-heh... Kyuu", she let out a weird sound before collapsing.

"Mio!!!"

"Alright... I'm tired of this now. Hey you, Miyamura the older, get out of this room and go to class already.", said Koyuki-san.

"B-But Mio is-"

"GO TO CLASS"

"Yes, ma'am"

During break time...

"Oi! Yuuji! Are you alright?"

"Who is i- Ah, it's just Haruto."

"What do you mean by 'it's JUST Haruto'?!?! I, Haruto the great, have given you a fraction of his time out of his concern. Aren't you going to feel grateful?!?!"

"Scram."

"Fine, fine. I'll just keep the drama club practice for myself. Jeez. Not even a sense of humour?"

"Scram."

"What's up with you today anyway?"

"M-Mio is-!!!"

"Oh, it's just about your little sister again, huh? Well, I'm off!"

"What do you mean by 'it's JUST about my little sister', huh? Do you think you're more important than my extremely cute sister?!?! Are you, huh?!?!"

"Why are you so obsessed with your little sister anyway?"

"Haven't you ever seen her smile? It's the most beautiful smile in the world. Her fragrant scent is also the best. Her sleek black hair is so beautiful when it reflects against the moonlight. Her eyes are like diamonds reflecting off the light of the sun! She's basically a piece of artwork made by God himself!!!"

"You siscon."

"I'm no siscon. I'm just someone who appreciates the beauty of my sister."

"... You're beyond help."

"I'll pretend I didn't hear that."

After that, the class continued as normal. Immediately after the class ended, I went straight to the back of the school. I have business to settle there.
