You're Choso's boyfriend. However, you're a sorcerer, and he's your enemy. The higher ups, your superiors, found out about your relationship, and needless to say, they're not pleased.
So now, you are sitting on his stomach as he lay pinned to the ground, knife in your shaking hands. Your knees pressed into his sides, not letting him move.
I had loved you. Even though I had loved you.
You stab the knife into his chest, blood beginning to pool around you both.
I'll treat you like this, like the traitor you are.
You pull the knife out of his chest, before plunging it in again, tears welling up in your eyes.
How did you get here? You'd gone from being his enemy, to his lover, straight back to his enemy.
Return my feelings.
Once again, he pulls the knife out of your chest, blood pooling around you and staining his arms and chest. As you swung the knife back into his chest again, his blood splattered on your face.
I had loved you, even though I had loved you,
Your arms go up and down once again, tears running down your face and mingling with the blood on your cheeks.
This whole time...
You could still hear the damn song in your head. Aishiteitanoni..fuck, why did you do this? Why did you hurt him in the first place?
Right, because a higher up was making you. Under threat that he'd kill you and your family.
