While "Kareshi Kanojo no Jijyou" (1998) literally means "The Circumstances of a Boyfriend and Girlfriend", its actual (and official translation used by RightStuf International) is "His or Her Circumstances." While "kareshi" and "kanojo" both mean "boyfriend" and "girlfriend" respectively, they are sometimes used to mean "his" or "her." However, this practice is rarely used outside of textbook Japanese.
The director Hideaki Anno had a disagreement with the "Kare Kano" Manga author and the Gainax studio so he quit working on the anime in the last episodes. He was replaced by an another director.
The production of the series ran concurrently with the production of the manga so closely that when the production staff of the series caught up with the current events of the manga, they had to fill episodes with more and more recap filler in order to give the manga more time to develop.
Similar to Gainax's "Neon Genesis Evangelion", the later episodes had clip shows, lengthy recaps, still images and incomplete animation due to budget issues and conflicts with the manga author.
