Shiina-san, Numattemasu.

With both my parents passing away early on, I've spent my days working to support my younger brothers and sisters. One of the few things that helped me through this was fawning over my favorite character from a mobile game, and my boss, who happens to be the handsome and talented producer that created said game. But, one day he found out about my secret part-time job. If I'm fired, I can't pay the bills. If I can't pay the bills, we'll be out on the street...!!! But instead of exposing me, he makes me an offer. The deal? Become his housekeeper. I didn't think that would include putting him to bed though...?!
