Episode 10 Story

With Ozuma’s help, Akiteru sneaks into the Kohinata household at night. His mission is simple: to reconcile with Iroha.

But no matter how many times he calls out, Iroha refuses to leave her room. That’s when Akiteru decides to use the most efficient method he can think of—

The battle to make his friend’s little sister “annoying” again begins now!

Introduction

No need for shallow camaraderie, no girlfriend required, and only one true friend is worth having.

That’s how I, Akiteru Ōboshi, live my youth, discarding anything “inefficient.”

And yet, there’s someone who insists on hanging around my room.

Not my sister, not a friend, but an annoyingly clingy underclassman: my best friend’s little sister, Ayaha Kohinata.

“Senpaai, let’s go on a date! …Or did you think I’d say that?”

With the energy of someone who seems to have energy drinks flowing through her veins instead of blood, she invades my bed, teases me with half-hearted seduction, and generally pesters me nonstop. I’m busy every day, but she doesn’t care in the slightest.

Still… why does everyone keep giving me those envious looks?

Apparently, outside of my room, Ayaha is insanely popular, a bright, top-ranked honor student who’s kind, considerate, and the very picture of a pure, elegant girl.

Hey, seriously… if that’s who you really are, then why are you only this annoying to me?
