Hidamari Sketch, A-Channel Recommendations
You can't really go wrong with this two. Both based on manga from Kirara, the tasty shoujo-ai magazine for male demographic, both shows are similars in too many ways.
Hidamari cast start off with four characters. The airhead, the cute, the cutely wicked ,and the cutely bullied. That's pretty much the same with A Ch.
Their activities is based on schoolground, added with on-location cuteness anywhere they go, meaning their settings is exactly the same, small Kirara style world with women to men ratio 20:1.
They love each other a lot. It's likely you won't see your (real 3D) lady friends express their affection for each other
Each has an easy pace to them making them both easy to watch and re watch countless of times. They primarily focus on a circle of friends theme and how good friends interact with each other while again throwing out random situations. The characters Yuno and Tooru are similar here as each have a strange friend who tends to be outlandish at times Miya=Yuno : Run=Tooru.
