Blade Runner 2049: Luv's name symbolises this trope like love she can be gentle, kind and passionate but at other times she’s cruel, obsessive, violent and traitorous. Yet in even in act of violence, Luv cries Tender Tears which reflects how double sided love is. This also contrasts with the other female character whose name is “Joi” who represents pure positive emotion thus its fitting when towards the end of the movie where Luv literally destroys Joi.
Speaking of Joi, her relationship with the Replicant protagonist K screams this trope, in spite of both of them being artificial their love for each other is genuine. Therefore their love mixed with tragedy since Joi is a hologram whom K cannot touch and her feelings may be completely manufactured. Then again the moments before Luv destroys Joi, he reaches for her and she reaches for him saying she loves him before being removed from existence by Luv. While it’s up for audience interpretation, K and Joi’s feeling were real to them which is what really counts.
