Best Fairy Doctor

When I asked my master why he wants me to study medicine? He said "Because you can't find a wife normally these days, if you have these skills, you can get into touch contact with girls" I mean what a pervert, right? But I too am a pervert, as I usually peek at my Senior sister while she takes bath. But I am also a Gentlemen who treats girls with care, that's why they call me A Gentleman Pervert. In this way, I learned superb medical skills and came to city to find a wife...if possible a Harem?
