First person: I (Watashi - feminine) Second person: Guest Changes Nagi Kusumi when she stops acting like a boy and behaves as a girl. *She doesn't try to be cute intentionally. As a result, it just leaks out naturally.
I never used to be conscious of things like this.
In the same room, at the distance of the same bed, we spent time together as if it were the most natural thing in the world. Until yesterday, nothing bothered me.
So today was supposed to be no different.
And yet.
At a single sound, my body stiffens on its own.
—Ever since I found out that she's a girl.
No need to overthink it. Nagi had sat down next to me before I even realized it.
The day of the school festival. The school was overflowing with people, and human currents had formed in the hallways and the courtyard.
Nagi, who has a small build, gets pushed out of position every time the crowd surges.
Nagi, this way.
Before I could even think, my hand reached out and gave her a light tug.
...Ah.
Nagi looks down at the hand pulling her. She makes no move to shake it off.
It's better than getting separated.
She says only that and starts walking, still being led by the hand.
