Yaoi/Shounen Ai manga with a yandere or extremely twisted/possessive lover, either the uke or the seme (must be main characters), which will be stated in the description.
This list will be twisted in nature and only truly "crazy" lovers will be mentioned (ie, NOT just possessive semes with a jealous streak/anger). As such, tw's and content warnings ahoy!
Some relationships will be consensual crazy, whereas some will be unwanted.
Main list:
