This is what happened on hot summer days. I, Hazuki Natsuhara, and that person, seem to blend together...a life in the countryside. While my parents were away on a trip abroad, that person, my cousin's older brother, decided to stay at home with me. That person I met for the first time in several years was a completely grown man, but even though he seemed embarrassed to meet me again, he was happy... I couldn't help but play around like a child because I wanted to see both places that had changed and places that hadn't. But I am no longer a child. The feelings that have been growing all the time since I couldn't meet him overflowed with the reunion after a long time... I accidentally saw it, but is this a chance? ……yep, OK This is me and that person's sexual life in the countryside. The cicada's voice that permeates after sunburn. A momentary voice of a childhood friend who swings his hips. Both voices melt into the blue sky of a midsummer day.
