Ayumu feels like a goose with her clingy and school's popular Shiratora brothers. Only 1 chapter is available so far. I wonder if the scanlators meant duckling. Anyway, the animal reference is not something new since it's from the same mangaka who wrote other two reverse harems: Ookamidomo no Shitsukekata (wolves) and Bokura no Himitsu wo Kyouyuu shiyou ka (animal love story). I don't remember really liking her art before but I sure do now.
