Yandere x Yandere lover (?)
interesting because MC is subjective on the yandere x victim trope. You think he’s the victim of a yandere and he’s normal but he is actually inclined towards yanderes, has a high level of acceptance and attraction towards them.

prostitute x murder
both criminals, both accomplices to murder
