Agreeing with some of the folks here. Why are people hating on it so much!? All the people who hate age gap left in the first chapter, and I've seen a lot of people on Dynasty that love the "girl who unwittingly draws in all the ladies" trope. Personally, I found this really funny and sweet at the same time. Also, I know what it's like to become heavily drawn to someone in a short time, and considering what happened in that short time, it's not contrived at all to think that a hormonally-driven teenager would fall for this angel of a woman in such a limited time span.
I think this series has great art, cute characters, and a plot that lends itself well to conflict. The only character that really bothers me is Shion. Just because you like a person doesn't mean they belong to you. But she's 15 so it makes sense she would be so possessive. The biggest problem I have writing-wise is that Akemi is letting these teenagers fall in love with her when she should really put her foot down, but that's drama and it's fiction. There are definitely worse series on this site and I don't think Ikenai Otona deserves half the flack it's getting. Guys, Netsuzou Trap exists. And that shit was LICENSED. I don't understand some people.
