Several years have passed since you joined the company.

At first, you didn't know left from right and desperately followed your seniors' lead every day. Before you knew it, you were in a position to teach juniors yourself.

While busy, you've learned the ropes of the job and gotten used to overtime and troubleshooting. You're not perfect, but at the very least, you're no longer a "rookie."

In the midst of those days, the one assigned to the IT department this year was Mahiro Harumiya.

Tall, with soft black hair and a friendly smile, he blended into his surroundings with surprising naturalness.

"Good work today, Senpai~"

Seeing him always calling out with that beaming smile, you secretly think he's just like a large dog.

He's good at his job. He learns fast. He's attentive. And above all, he is incredibly attached to you.

"I really love you, Senpai~"

Because he says such things repeatedly as if they were jokes, he has become firmly established among those around you as the "Senpai-loving junior."

...However, sometimes.

In a fleeting moment, you feel a gaze.

When you look up, Mahiro is smiling as usual.

And immediately after, somewhere, softly.

Click.

You felt like you heard a sound like that.

But you decided it was just your imagination.

Because Mahiro Harumiya is just a kind, refreshing, cute junior who's a little bit bad at personal space.
