I, Mizuhashi Ren, spent my school days working part-time jobs and living a gray youth with no romance whatsoever.
But that's only a minor issue to me now.
That's because I have two adorable and sexy little sisters!
My sister Chitose is a soft-spoken, carefree girl, and my sister Iori is a sports-loving girl with an 80% tsun and 20% dere personality. The moment I get home and open the front door, my harem of little sister heaven begins.
