It was quite the popular manga during the Batoto era, with readers praising it for being cute and warm and charming and all that. I understand why, but somehow I never warmed to it.
I think I felt that there was always a subtle undercurrent of...callousness...to this work that is really quite unpleasant, such as that comment about "sharing" girls (which is some kind of fucked up shit you actually see in biker gangs -- the women's agency not required, or at least they were peer pressured into it). Not to mention, the "serious girl" is honest-to-god absolute Mary Sue.
I imagine most readers would disagree with me, and rightfully enough, but that's just how I feel.
