From ALC:

I became slave to a rich girl!? The vivid Harem Love story of the idiosyncratic clique in a women's dormitory!! It will be too much as hearts throb…girl's lips are soft aren't they…feelings and body melt together… In Mikuni Hachime's “ecchi” comedy Gokujō Drops, Maezono Komari runs into housing issues at school (haven't we all?) and finds herself accepted, conditionally, in the fanciest dorm on campus. The sole condition? That she act as servant to school star Himemiya Yukio. That's tolerable, but the sexual harassment is just beginning…worse, Komari is starting to have feelings for Yukio!
