[b]Obsessive Love[/b] (or [b]Obsessive Love Disorder[/b]) is a condition where a character has been driven into [[crazy|insanity]] by an overwhelming obsessive desire to possess and protect another person, with an inability to accept [[fail]]ure or [[rejection]]. Depending on the intensity of their affection, obsessive lovers may feel entirely unable to restrain themselves from extreme behaviors such as [[violence|acts of violence]] toward themselves or others.

In the anime and manga fandom, including danbooru, the term [b][i]yandere[/i][/b] (from [i]yanderu[/i], meaning [[crazy|mentally sick]], and [[deredere]], meaning [[lovestruck]]) is used to describe that character trait (and sometimes an over-dramatization of it). Usually, they are [[guro|extremely brutal]] and do not hesitate to [[attack|hurt]] and/or [[murder|kill]] others in order to be with their beloved.

[b]This tag is for characters who go insane from obsessive love.[/b] If the character in question is insane because of other reasons, use [[crazy]] instead.
