I thought it was very cute and fluffy and realistic from what friends of mine have said. I grew up in a very small conservative farming town where religion dominated everyone's lives. You can tell there was little to no education at home or school by the large number of early teen pregnancies. This was on both the male and female side. We taught our son starting at age 12, and even that may be starting late these days in America, about sex, masturbating, treating the opposite sex with respect, love, etc. Wish more parents would proactive.
I can't tell what the other manga you are working on, but if it's yuri, it needs to be here!
