I actually bought the manga called "Kodomo no Jikan(こどものじかん)" or in English Children's Hour. I did not finish the manga because there were only vol 1-6 available hard copy in my local book store. Even though I only read vol 1-6, I think Children's Hour is a great manga in terms of story.

(spoiler alert)
Children's Hour is about a teacher named Daisuke Aoki. He is a 23 years old teacher, who teaches grade–schoolers. Throughout his days, he always end up in a embarrassing(?) situation with rin, who is one of the student of Aoki. Those embarrassing situation includes kissing and some skinships (スキンシップ), which means "non-sexual touching between very close platonic friends" according to urban dictionary. Eventually, Aoki finds out why she act this way and soon he started to care about her and almost love her....

I know some people are disgust about how Kodomo no Jikan, the author, draw a lewd loli. One might even say it is straight up lolicon doujinshi(同人誌), but I still respect him because the visual and the entertainment (° ͜ʖ°). Plus, I personally like lolis because of their cuteness😏😏😏. I rate this manga 8/10 and I would recommend this to loli lovers :D
