An old man who cherished me like a real daughter after I lost my father in a car accident when I was a child. I suddenly wanted to see him so much that I visited his house, and I realized the existence of a special emotion different from the one I feel for my father. But no matter how much I tried to seduce him, the kind old man wouldn't lay a hand on me, and when I finally forcibly took his lips... Our summer, wearing yukatas, setting off fireworks, eating watermelon, and intensely connecting with each other.
