I used to love her, but I had to kill her
I had to put her six feet under
And I can still hear her complain...
Here's another one :)

This may fit. First of all there's a scene in the music video but here are some lyrics that jumped out at me
https://lyricstranslate.com/en/synkyet-aizou-no-famufataaru-lyrics.html
純粋な天使のような笑顔さえも傷ついた僕の心は歪みを生む "Even an angelic smile, pure as can be, can wound my heart, giving birth to distortion"
群青が滲む時間に君を拐いどこまでも誰も知らない場所へ "In the indigo-blurred moments, I'll kidnap you, to a place no one knows."
Ah 怯え震える君が愛しい "Ah, I cherish the way you tremble in fear,"
Ah 閉じた部屋で君を奪って "Ah, in this closed room, I'll steal you away."
張り付けられ掠れてく叫びは地に堕ちる憎しみ残したまま "The screams, clinging and fading, fall to the ground, leaving behind lingering hatred."
You can check out the entire song yourself if these aren't convincing enough
I know one https://lyricstranslate.com/en/little-piece-heaven-lyrics.html
I think. Eventually they killed each other so, I don't know if it counts.
