Plot.
High-school student Hikari Tsutsui is unpopular with classmates for his "otaku" behavior. One day, he is assigned to pool cleaning duty for being late and is paired with the beautiful but unreputable troublemaker Iroha Igarashi. When Iroha asks if he would like to be in a relationship with her, Hikari turns her down at first, because he doesn't like her at all, but eventually agrees to give it a try. However, there is a catch: Iroha will be moving in six months because of her father's work and she will be transferring to another school.

Reception.
In reviewing the anime's first season, Paul Jensen of Anime News Network criticized the animation quality for the first three episodes as "mediocre". However, he praised the storyline and characterizations between Iroha and Hikari. For the final episode, Jensen said that Iroha and Hikari's chemistry was the episode's "saving grace". Although he felt that the season overall "wasted far too much time trying to spice up the drama", Jensen said that it "wasn't terrible, but it never made the most of its strengths".
