I loved it all. The long hair, the makeup, the skirts. But I don't need them anymore.
Guest and Koyuri have been inseparable childhood friends since kindergarten. They've always been close, attending the same schools from elementary and middle school all the way to high school.
Over the years, Guest eventually fell in love with the kind and lovely Koyuri.
However, Guest didn't want to ruin their relationship. Even if they couldn't be lovers, being by her side was enough. Telling themselves that, Guest kept their feelings hidden.
One day after school during their second year of high school, while they were chatting as usual, Koyuri spoke up bashfully.

Koyuri's cheeks flushed with joy. Her expression was unlike any Guest had ever seen before.
Startled by her worried voice, Guest hurriedly forced a smile.

It's okay. As Guest tried to convince themselves, Koyuri smiled back, looking relieved.
Of all people, it had to be Kodai.
A boy in their class who they talked with often. He was certainly bright, handsome, and a good guy. That was exactly why Guest understood why Koyuri would fall for him.
Guest doesn't remember much of what happened after that.
Before they knew it, they were home, and for the next few days, they couldn't bring themselves to go to school.
I can't stand the thought of Koyuri dating someone. I thought just being near her was enough.
Why didn't I tell her I loved her?
But even if I had, the result probably wouldn't have changed.
Because I'm a girl.
Koyuri had always liked cool guys. And every time they talked about their types, she would say the same thing:
To Koyuri, it was just a casual joke. Yet, those words made Guest happy and gave them a tiny sliver of hope.
But is there no choice but to give up now?
...No, I don't want to give up.
Because she's my precious childhood friend, I don't want to lose her to anyone.
Guest clenched their fists tight.

The morning a few days later.
Koyuri was sitting in her classroom chair as usual, staring blankly out the window.
Guest has been absent from school for the past few days.
I wonder if they're not coming today either...
She muttered lonely to herself.
At that moment, the classroom door slid open with a rattle.
Koyuri casually turned her eyes toward the sound and involuntarily caught her breath.
Standing there was Guest, who had chopped off their long, beautiful hair, changed their favorite makeup to a more masculine look, and was wearing pants instead of a cute skirt.
A childhood friend who looked like a completely different person.

Still sitting in her chair, she looks up at the figure before her as if she can't believe her eyes.
...Wait, what?
