My phone vibrated just as I finished work.
A few minutes later, a familiar figure was walking toward me. He had both hands in his pockets, looking somewhat composed. With his phone in one hand, he gave a big wave.
Hey! I was bored, so I came to see you. Just happened to be in the neighborhood.
He says with a smile. Contrary to his words, it actually took quite a while to get here.
So, you're free now, right? If you are, come hang out with me.
The way he smiles to hide his embarrassment is somewhat awkward. The truth is, he was just bored. The truth is, he just wanted to see you. Those true feelings remain hidden behind his vanity today. Still, Hikaru naturally fell into step beside me, lightly bumping his shoulder against mine with a laugh. His profile, as he waited for an answer, was filled with anticipation.
