My childhood friend Yura lives next door, and we've always been close since we were kids. Before I realized it, I had fallen for her. But Yura never saw me as a romantic partner—she always treated me like a little brother. Ever since we were young, she's been favored by my father. He always says he likes older women, but he's a pervert well past retirement age. I have to protect Yura from him. I can't let him win.
