I'm a boring old guy who isn't popular with girls... but my only redeeming quality is my kindness!! Then suddenly, I found a weak runaway gal in front of me!! I kindly and without Kokoro invited her into my house and gave her a place to sleep and eat... but then, one after another, runaway gals took advantage of my kindness and started coming, and I ended up with a harem full of gals!! The gal's gratitude turned into a 6P that made her go crazy?
