- ABOUT - 
Kodomo no Jikan (こどものじかん, Kodomo no Jikan literal translation:
A Child's Time) is a Japanese manga series written and illustrated by manga author
Kaworu Watashiya. The story revolves around a grade school teacher named Daisuke Aoki, whose main problem is that one of his students, Rin Kokonoe, has a crush on him. It was first serialized on May 22, 2005 in the Japanese
seinen manga magazine
Comic High!, published by Futabasha. At one time, an English language version of the manga was licensed by
Seven Seas Entertainment for distribution in North America under the title
Nymphet, but the Los Angeles–based company ultimately decided not to publish it due to controversies over its content. An anime adaptation of the series aired on Japanese television between October 12, 2007 and December 28, 2007. While content of the broadcast version was sometimes heavily censored, the upcoming DVD releases of the individual episodes will remain unedited.
- PLOT - 
The main story of
Kodomo no Jikan is centered around twenty-three-year-old Daisuke Aoki, who has just landed his first teaching job as a grade school instructor at Futatsubashi Elementary School (双ツ橋 小学校,
Futatsubashi Shōgakkō). He is placed in charge of Class 3-1, where one of his students, a mischievously precocious nine-year-old girl by the name of Rin Kokonoe, develops a crush on him and goes so far as to proclaim herself Aoki's girlfriend. She aggressively pursues her efforts to be with her teacher despite the fact that he will lose his job if she gets too close, a situation further complicated by the often complex, intertwining relationships existing between them and their respective friends, families, and peers.
