I was visiting a rural town with my dad, where our neighbors, with whom we used to be close, had moved to. ...That's because I'd heard through the grapevine that their father had passed away. Yet, inappropriately, I was happy to see our neighbor Nagisa-chan again after so long... Yes, I had a crush on Nagisa-chan, my childhood friend who had always called me "big brother" and looked up to me.
