'yandere' is a catch all term for characters who become obsessively lustful/loving of a partner
They are manic and frantic in expressing this love/lust towards their target, and often times obsess over, stalk, and attempt to isolate their target by means of kidnapping their target and murdering perceived competition.
Basically, an obsessed stalker who wants you all to themselves, sexually, romantically, and they will NEVER let you go.
