bet if this was loli there wouldn't be as much complaining in the comments...
In addition: I think it would have been acceptable if the romance thing was one sided, since it's pretty normal in anime/manga culture for children to be obsessed with grown-ups. Kouhei actually being flustered because of a child does make it kinda creepy.
I don't see a lot of manga like this but in doujins, so I'll just choose to ignore the creepy factor and enjoy it for what it is I guess...
As of making this edit, I have just finished chapter 14. Based on how this creepy shit will lead to, I may or may not drop this series.
another edit: Yeah this is getting a little too pedo for me.
