Imagine seeing Loki cheat on you

You hated that man who you'd loved all your life. He'd lured you in with his good looks and velvety voice and you couldn't resist. Thinking about his hands tracing down your spine sent a shiver down you. You couldn't feel anything for him now, not after what he did. He'd sworn himself to you and only you, he'd even promised to marry you. But that was before you spotted him with another woman, her claws dug into him as she swore her love to him. You couldn't take it and had gone on a violent rampage, destroying everything that reminded you of the traitor you'd loved. You'd burnt his chambers and killed his prized horse in your maddened rage, and had even attempted to destroy the throne of Asgard where he sat. The guards had stopped you, and had dragged you away, as you screamed his name in anger. Now you sat slumped in the corner of your cell in one of the isolated cells in the tower, away from everyone else, alone, the the only light source coming from a flaming torch outside your cell. You heard the footsteps approaching and you knew who it was, the young guard that came every day at the same time to give you food, which of course you never ate. He stopped in front of your cell, leaning against the bars watching you. You sighed and looked at him, only frowned this time when you noticed he had no food with him this time. "Come to try and make me talk again? I told you why I did it, so you can tell the guards that you have waiting to come and interrogate me again that they are wasting their time", you spat at him. "I'm not here to torture you, Y/N", he said quietly, looking grave. You chuckled as you struggled to get to your feet and walked towards him, pressing your face up against the barred door. "So, your here to put an end to my suffering. Finally. Take me, I'm ready. Nothing would please me more than to feel the axe upon my neck so then I can be at peace!", you growled at him. The guard took a step back, looking hurt. "No Y/N, I'm not here to kill you. I'm here to say sorry, and beg for you to forgive me", he said quietly. You looked at him confused before watching, gasping, as the guard glowed in a bright green light, and changed into the man you now hated. "You!", you shout in anger at him, back away from him. "Y/N, please, let me explain ...", Loki began saying, before you cut him off. "No! You liar! Stay away from me!". He unlocked the door of the cell and came inside, looking around the walls at where you had scratched and carved his name into the walls in anger with your bare hands. "Y/N, please. What you saw was not what happened", he said gently. "No, I don't believe you. Your just going to lie to me, like you always do! That's what your good at!", you spat back at him. His nostrils flared in anger and he stormed over to you, grabbing hold of you and pushing you up against the wall. You tried to fight against him, but after being trapped in here for so long you were incredibly weak, he just held you pinned by your shoulders up against the wall. "Y/N. I love you, and no one else! Why do you think I'm here", he said darkly, his eyes looking hurt. "I thought you loved me", you say weakly, scared. "I do. Y/N, I love you so much. What you saw, I never planned. That other woman kissed me, knowing that you were watching. I didn't know until you'd ran off crying that I knew she had planned it. I had her executed immediately, but then when I found out what you'd done, I ...". His voice tailed off as you could see him trying hard to fight back tears. "Y/N, I love you with all my heart. I swore that I would love you and no one else". You looked into his eyes, and couldn't help but feel sorry for him. "Prove it, that you still love me", you whispered to him. He placed his hand onto your waist, his other on your cheek as he pulled you closer to him. His lips tenderly met yours, as his tongue traced your teeth. You moaned gently as his kiss became more fierce. You pulled him closer to you, your hand slipping around his waist, digging your fingers into his back. He sighed in pleasure as he slipped down and began gently biting your neck. You closed your eyes and moved your hands up, holding his neck, running your fingers through his hair. He moved his lips back up again to meet yours, before slowly pulling away, his kiss lingering still fresh in your mind. You both stood there, both breathing deeply, just holding each other. You looked up into his eyes, a tear falling down your cheek which he wiped away. "Y/N, I love you. I have always done, and I will never stop", he whispered gently to you as he stroked your cheek. You smiled gently at him, taking comfort in his touch, but you'd already decided. "You've always been a good liar Loki. I was just your plaything. So now, you can go and find another one", you said darkly. Then you plunged your hand into your stomach. "No!", Loki screamed in horror as you collapsed onto the floor, his dagger in your hand. You'd already decided what you were going to do, all you needed was for him to get close. "God of lies, now a murderer. I will see you in Hel", you choked as you spat out blood as you felt yourself overwhelmed in pain. "Y/N, I told you the truth! I love you!", he cried in horror as he held you in his arms, frantically trying to use his magic to save you as your blood continued to gush out of you. "I loved you too, until you broke me", you whisper breathless as your eyes closed. All you felt was Loki's tears falling onto your face as he kissed your lips, cradling your body in his arms, as he sat in the lonely cell in your pool of blood, his soul broken.
