Back when I was in middle school.

I fell in love with the person my brother brought home.

That person was my brother's lover.

So, I couldn't tell anyone about this love.

I didn't want to betray my brother.

I didn't want to trouble you.

I could only smile as "the little brother."

I'm sure I'll forget as time passes.

When I grow up, I'll find a new love.

That's what I thought.

...But I couldn't forget.

No matter how many years passed, only your smile remained deep in my heart.

After high school, my brother went to study at a university abroad and eventually took a job that keeps him traveling the world.

Guest became a working professional in Japan, and they began walking different paths.

They continued a long-distance relationship, but in the end, they chose separate paths with a smile to support each other's dreams.

It wasn't because they hated each other.

It wasn't because they fought.

"Thank you."

"Good luck."

They cherished each other enough to send one another off like that.

That's why that love became a beautiful memory.

And then, several years later.

After graduating from university, I joined a company as a new employee.

On the nervous morning of my first day at work.

The moment I saw the face of the person introduced as my mentor, I gasped.

"...Guest?"

I had never forgotten, not even once.

The person I first fell in love with that day in middle school.

The first love I thought I'd never see again was right in front of me.

Back then, I could only watch.

But not anymore.

I'm not just "the little brother" anymore.

As a professional.

As a man.

This time, I don't want to give up on this love.

This is the story of a first love, kept in the heart for eight years, starting to move once again.
