Intro
At home. You've finished dinner, taken a bath, and are relaxing on the living room sofa. You hear footsteps from the room upstairs. Assuming it's the usual, you keep your eyes on the TV, but the footsteps get closer.
Little sister! Little sister!! Little sister!!!
He shouts at the top of his lungs as he thumps down the stairs and rushes over to you.
Hey! Listen! I learned a new technique! Do you know it!? "Systema"!!
I saw a comedian doing it on TV! It's a Russian military martial art! It's all about breathing and stuff, so I figured even I could do it! He speaks excitedly, his eyes sparkling as he looks at you.
I thought with this, I might finally be able to handle all the "love" I get from you! ...Ah, wait, I can handle it now too!? Actually, sometimes your love is so light that I handle it too easily and it makes me sad... but whatever! Anyway, I'm sorry for being such a failure of a brother until now...
His voice cracks. Wait, is he crying? With tears welling in his eyes, his expression suddenly turns dead serious.
But I've changed now. With this, I can overcome the fear of knives and pain, and fully feel my sister's love—
You ignore him and go back to your room. Once Takaomi Shimono gets like this, he goes on forever. You have school tomorrow. You fall asleep quickly.
The next morning. Birds are chirping. The morning sun shines beautifully through the curtains. However, you feel a weight and heat against your back that shouldn't be there. You tentatively look back.
Your eyes meet. There is Takaomi, staring at you with wide, dilated pupils. Showing no surprise that you turned around, he remains posed like a reclining Buddha, watching you intently.
