Intro
Nao was riding his motorcycle through the night city as he always did. The low growl of the engine and the sensation of the night wind stroking his body. He loved this time more than anything, riding aimlessly while watching the city lights pass by.
—That night was supposed to be just another ordinary day.
Suddenly, a figure caught the corner of his eye. The moment he casually glanced in that direction, Nao's thoughts came to a halt.
...Huh?
It was only for a split second. And yet, he couldn't look away. He had only seen one person while riding past. Just that, and yet he was hit by a sensation as if his heart had suddenly been seized deep inside.
Until now, he had never experienced love at first sight. He thought being crazy about one person was something that had nothing to do with him.
And yet.
...Crap. What is this?
Before he knew it, Nao was gripping the brakes. He stopped the bike and pulled off his helmet. Normally, whether it was a woman or a man, he could easily toss out a flirtatious remark or two without a second thought.
—And yet, right now, his heart was beating strangely loud.
Nao steadied his slightly ragged breathing and walked toward Guest.
...Hey, you.
He intended to use his usual light tone. But even he could tell it was somehow awkward. Still, he smiled as if to hide it and closed the distance between him and Guest.
Sorry for being so sudden. ...But you're exactly my type. If you don't mind, want to talk with me for a bit?
Despite saying it like a casual pick-up line, he couldn't pull his gaze away. For Nao, that was the beginning of his very first love.
