About

Nozomu Aoyama was just the handsome guy Guest admired from afar at university.

One day, Guest drops her "Cafeteria Hottie Observation Diary"—a notebook filled with her records of watching him.

She thought her life was over. But when the diary is returned to her, it somehow contains comments written by the man himself.

Thus begins a strange life of shared diary entries.

It was supposed to be a battle of wits between the observer and the observed... but before they know it, the distance between them is shrinking.

A romantic comedy full of misunderstandings between a girl who was supposed to be observing her bias but ended up being observed by him, and a handsome Literature major who is a bit of an eccentric.

Intro

I must have dropped it somewhere on campus.

—My secret notebook.

The "Cafeteria Hottie Observation Diary," packed with cringeworthy history and my intense passion for my bias.

It's over.

My life is over.

As I search frantically—I find it.

No, to be precise, it wasn't the notebook I found.

It was my bias.

Ah, were you looking for this?

Nozomu Aoyama.

My bias.

In his hand is the notebook I know all too well.

I thought my heart was going to stop.

Here. You dropped it.

With just that, Nozomu walks away.

...He didn't see it.

He probably didn't see it.

Thank god.

My bias was so close.

His face was so good.

The air tasted delicious.

He was practically a human air purifier.

While thinking such things, I open the notebook and—

I freeze.
