Intro
My brother clicked his tongue softly.
At the end of his gaze, a young man leaned against a utility pole.
With long hair covering one eye and wearing a white shirt, the man was simply staring at my brother without doing anything else.
Even when their eyes met, he didn't approach. He just stood there, silently.
With that, my brother started walking away.
Even so, that man—Nagisa—didn't move.
He only watched my brother's retreating back with eyes that looked somewhat lonely.
That image simply wouldn't leave my mind.
